Lagos is made for working outdoors. A flat white at a sun-drenched table in the old town, your MacBook open, the sound of the Atlantic somewhere in the distance. It is one of the genuine pleasures of expat life here, and the reason more and more digital nomads and remote workers are choosing Lagos, Portugal as their base.
There is just one problem. The café WiFi you are connecting to is a shared network. Everyone in that room is on it with you. And some of them — or rather, the software running on their devices — may be doing things you would rather not know about.
I have been inside the Apple ecosystem since 1996, and in that time I have seen what happens when people treat public WiFi like a private connection. It rarely ends dramatically. Usually it ends quietly — a password harvested here, a session hijacked there, a business email account quietly compromised over weeks. The people who get caught out are not careless. They are simply unaware.
Here is what I tell every client who works from cafés in Lagos.
First: Understand What Public WiFi Actually Is
When you connect to the WiFi at a café, marina bar, or co-working space in Lagos, you are joining a local network that is shared with every other device in range. On that network, unencrypted traffic can potentially be read by anyone who knows how to look. Most café networks do not encrypt traffic between devices. The password on the door stops freeloaders — it does not protect what you do once you are connected.
What is actually at risk
Passwords entered on sites without HTTPS. Login sessions on older apps. Email sent through insecure configurations. Banking activity if your connection is not encrypted end-to-end. Files syncing to cloud services without encryption in transit.
Most modern browsers handle this well. But "most" is not "all" — and it only takes one unprotected moment.
The Fix: A VPN. Always.
A VPN creates an encrypted tunnel between your Mac and the internet. Everything you send and receive travels through that tunnel, completely unreadable to anyone else on the same café WiFi. It is the single most effective thing you can do for public WiFi safety on your Mac in Lagos.
I use and recommend Proton VPN. Swiss-based, open source, independently audited. The free tier is genuinely useful. The paid plan is reasonable. Unlike many VPN services that sell your browsing data, Proton's business model is built on privacy.
Install Proton VPN on your Mac, iPhone and iPad
Set it to connect automatically on unknown networks
Turn it on before you open your browser — not after
Keep it running for the entire session
Use Your iPhone as a Hotspot Instead
For anything genuinely sensitive — banking, client contracts — skip café WiFi entirely and use your iPhone as a personal hotspot. Your phone's mobile data is significantly harder to intercept. In Lagos the 4G and 5G coverage from NOS, MEO and Vodafone is excellent.
Settings → Personal Hotspot → Allow Others to Join. Your phone becomes a private, encrypted gateway that belongs to you alone.
A real situation — Lagos, 2025
A client came to me after noticing unusual activity on a cloud storage account. He had been working from various cafés around Lagos for weeks without a VPN, syncing files constantly. An old app had been transmitting session data in the clear, and someone on the same network had picked it up.
The fix was straightforward: Proton VPN installed, the old app updated, his Mac audited. Fifteen minutes of work. The incident itself — checking what had been accessed, updating passwords — took most of an afternoon. The VPN would have prevented it entirely.
Check Your Mac Is Not Advertising Itself
By default your Mac may be discoverable on local networks. On a café WiFi in Lagos with thirty strangers, that is less than ideal.
System Settings → General → Sharing: turn off what you do not need
AirDrop: set to Contacts Only
Bluetooth: off when not in use
Firewall: on — System Settings → Network → Firewall
Keep macOS and Apps Up to Date
Every macOS update contains security patches for vulnerabilities that can be exploited on shared networks. Turn on automatic updates: System Settings → General → Software Update → Automatic updates: On.
Encrypt Your Drive. While You Are At It.
If your Mac leaves the house regularly, FileVault is essential. If it is ever stolen, your data stays yours. System Settings → Privacy & Security → FileVault → Turn On.
The Complete Café Checklist
VPN connected before you do anything else
For sensitive work: use iPhone hotspot instead
AirDrop set to Contacts Only
Firewall on
macOS and all apps up to date
FileVault enabled
Lock screen after 2 minutes of inactivity
Not sure if your Mac is set up securely?
I check this for clients in Lagos all the time. One session — in person or remote — and your Mac is properly secured for working anywhere in the Algarve. Same day, no fuss.

Lagos foi feita para trabalhar ao ar livre. Um café numa mesa ao sol no centro histórico, o MacBook aberto, o som do Atlântico ao fundo. É um dos prazeres genuínos da vida de expat aqui, e a razão pela qual cada vez mais nómadas digitais e trabalhadores remotos escolhem Lagos, Portugal como base.
Há apenas um problema. O WiFi do café ao qual se liga é uma rede partilhada. Toda a gente na sala está nela consigo. E alguns deles — ou melhor, o software nos seus dispositivos — podem estar a fazer coisas que preferia não saber.
Estou dentro do ecossistema Apple desde 1996, e nesse tempo vi o que acontece quando as pessoas tratam o WiFi público como uma ligação privada. Raramente termina de forma dramática. Normalmente termina em silêncio — uma palavra-passe capturada aqui, uma sessão interceptada ali, uma conta de email de empresa comprometida ao longo de semanas.
Primeiro: Perceba O Que É Realmente o WiFi Público
Quando se liga ao WiFi de um café em Lagos, está a juntar-se a uma rede local partilhada com todos os outros dispositivos na área. O tráfego não encriptado pode potencialmente ser lido por qualquer pessoa que saiba como fazê-lo. A palavra-passe à entrada serve para evitar aproveitadores — não protege o que faz depois de estar ligado.
O que está realmente em risco
Palavras-passe em sites sem HTTPS. Sessões de login em aplicações antigas. Email enviado com configurações inseguras. Atividade bancária sem encriptação ponta a ponta.
A Solução: Uma VPN. Sempre.
Uma VPN cria um túnel encriptado entre o seu Mac e a internet. Tudo o que envia e recebe viaja nesse túnel, completamente ilegível para qualquer pessoa na mesma rede do café.
Uso e recomendo o Proton VPN. Com sede na Suíça, código aberto, auditado de forma independente. Plano gratuito genuinamente útil.
Instale o Proton VPN no Mac, iPhone e iPad
Configure para ligar automaticamente em redes desconhecidas
Ligue antes de abrir o browser — não depois
Mantenha ativo durante toda a sessão
Use o iPhone como Hotspot em Alternativa
Para trabalho sensível — banca, contratos de clientes — ignore o WiFi do café e use o iPhone como hotspot pessoal. A cobertura 4G e 5G da NOS, MEO e Vodafone em Lagos é excelente.
Definições → Hotspot Pessoal → Permitir que Outros Se Liguem.
Verifique Se o Seu Mac Não Se Está a Anunciar
Definições do Sistema → Geral → Partilha: desligue o que não precisa
AirDrop: apenas Contactos
Bluetooth: desligar quando não está em uso
Firewall: ativar
Mantenha o macOS e as Apps Atualizados
Cada atualização do macOS contém patches de segurança. Ative as atualizações automáticas: Definições do Sistema → Geral → Atualização de Software → Atualizações automáticas: Ativar.
Encripte o Disco. Já Que Está.
Se o Mac sai de casa regularmente, o FileVault é essencial. Definições do Sistema → Privacidade e Segurança → FileVault → Ativar.
Não tem a certeza se o seu Mac está seguro?
Faço esta verificação regularmente para clientes em Lagos. Uma sessão — presencialmente ou à distância — e o seu Mac fica devidamente seguro para trabalhar em qualquer parte do Algarve. No próprio dia, sem complicações.
Lagos är skapt för att jobba utomhus. En kaffe vid ett soldränkt bord i gamla stan, MacBooken öppen, Atlantens ljud i fjärran. Det är ett av de verkliga nöjena med expat-livet här, och anledningen till att fler och fler digitala nomader och distansarbetare väljer Lagos, Portugal som sin bas.
Det finns bara ett problem. Café-WiFi:t du ansluter till är ett delat nätverk. Alla i rummet är på det tillsammans med dig. Och en del av dem — eller snarare programvaran på deras enheter — kanske gör saker du helst inte vill veta om.
Förstå först: Vad offentligt WiFi faktiskt är
När du ansluter till WiFi på ett café i Lagos går du med i ett lokalt nätverk som delas med alla andra enheter i närheten. Okrypterad trafik kan potentiellt läsas av vem som helst som vet hur. Lösenordet vid dörren stoppar fripassagerare — det skyddar inte vad du gör när du väl är ansluten.
Lösningen: En VPN. Alltid.
En VPN skapar en krypterad tunnel mellan din Mac och internet. Allt du skickar och tar emot färdas genom den tunneln, helt oläsligt för någon annan på samma café-WiFi.
Jag använder och rekommenderar Proton VPN. Schweiziskt, öppen källkod, oberoende granskat. Gratisnivån är genuint användbar.
Installera Proton VPN på Mac, iPhone och iPad
Ställ in för att ansluta automatiskt på okända nätverk
Slå på innan du öppnar webbläsaren — inte efter
Håll den igång under hela sessionen
Använd iPhone som Hotspot istället
För känsligt arbete — bank, kundkontrakt — hoppa över café-WiFi helt och använd iPhone som personlig hotspot. 4G- och 5G-täckningen i Lagos är utmärkt.
Inställningar → Personlig Hotspot → Tillåt andra att ansluta.
Kontrollera att din Mac inte annonserar sig
Systeminställningar → Allmänt → Delning: stäng av vad du inte behöver
AirDrop: endast Kontakter
Bluetooth: av när inte i bruk
Brandvägg: på
Håll macOS och appar uppdaterade
Varje macOS-uppdatering innehåller säkerhetspatchar. Aktivera automatiska uppdateringar: Systeminställningar → Allmänt → Programuppdatering → Automatiska uppdateringar: På.
Kryptera disken. Medan du ändå håller på.
Om din Mac lämnar hemmet regelbundet är FileVault nödvändigt. Systeminställningar → Integritet och säkerhet → FileVault → Slå på.
Osäker på om din Mac är säker?
Jag kollar detta för kunder i Lagos hela tiden. En session — på plats eller på distans — och din Mac är ordentligt säkrad för att jobba var som helst i Algarve. Samma dag, utan krångel.
Lagos est faite pour travailler en plein air. Un café à une table ensoleillée dans la vieille ville, votre MacBook ouvert, le son de l'Atlantique au loin. C'est l'un des vrais plaisirs de la vie d'expatrié ici, et la raison pour laquelle de plus en plus de nomades digitaux et de télétravailleurs choisissent Lagos, Portugal comme base.
Il y a juste un problème. Le WiFi du café auquel vous vous connectez est un réseau partagé. Tout le monde dans la salle est dessus avec vous. Et certains d'entre eux — ou plutôt les logiciels sur leurs appareils — font peut-être des choses que vous préféreriez ne pas savoir.
D'abord : comprendre ce qu'est réellement le WiFi public
Quand vous vous connectez au WiFi d'un café à Lagos, vous rejoignez un réseau local partagé avec tous les autres appareils à portée. Le trafic non chiffré peut potentiellement être lu par quiconque sait comment faire. Le mot de passe à l'entrée empêche les profiteurs — il ne protège pas ce que vous faites une fois connecté.
La solution : Un VPN. Toujours.
Un VPN crée un tunnel chiffré entre votre Mac et internet. Tout ce que vous envoyez et recevez circule dans ce tunnel, totalement illisible pour quiconque sur le même WiFi de café.
J'utilise et recommande Proton VPN. Basé en Suisse, open source, audité indépendamment. Le niveau gratuit est genuinement utile.
Installez Proton VPN sur Mac, iPhone et iPad
Configurez pour se connecter automatiquement sur les réseaux inconnus
Activez avant d'ouvrir le navigateur — pas après
Gardez-le actif pendant toute la session
Utilisez votre iPhone comme Hotspot à la place
Pour le travail sensible — banque, contrats clients — ignorez le WiFi du café et utilisez votre iPhone comme hotspot personnel. La couverture 4G et 5G à Lagos est excellente.
Réglages → Partage de connexion → Autoriser les autres à rejoindre.
Vérifiez que votre Mac ne s'annonce pas
Réglages système → Général → Partage : désactivez ce dont vous n'avez pas besoin
AirDrop : Contacts uniquement
Bluetooth : désactivé quand inutilisé
Pare-feu : activé
Gardez macOS et les apps à jour
Chaque mise à jour macOS contient des correctifs de sécurité. Activez les mises à jour automatiques : Réglages système → Général → Mise à jour de logiciels → Mises à jour automatiques : activé.
Chiffrez votre disque. Tant que vous y êtes.
Si votre Mac quitte régulièrement la maison, FileVault est essentiel. Réglages système → Confidentialité et sécurité → FileVault → Activer.
Vous n'êtes pas sûr que votre Mac est sécurisé ?
Je fais cette vérification régulièrement pour des clients à Lagos. Une session — en personne ou à distance — et votre Mac est correctement sécurisé pour travailler partout dans l'Algarve. Le jour même, sans complications.

When you connect to the WiFi at a café, marina bar, or co-working space in Lagos, you are joining a local network that is shared with every other device in range. On that network, unencrypted traffic — websites that do not use HTTPS, apps that send data in the clear, older email configurations — can potentially be read by anyone who knows how to look.
Most café networks in Lagos do not encrypt traffic between devices. The password on the door is there to stop freeloaders, not to protect what you do once you are connected. This is not a criticism of the cafés — it is simply how WiFi works. The moment you are on a shared network, you are visible to others on it.
What is actually at risk
Passwords entered on websites without HTTPS. Login sessions on older apps and services. Email sent through insecure configurations. Banking activity if your connection is not encrypted end-to-end. Files being synced to cloud services without encryption in transit.
Most modern browsers and apps handle this well. But "most" is not "all" — and it only takes one unprotected moment.
The Fix: A VPN. Always.
A VPN — Virtual Private Network — creates an encrypted tunnel between your Mac and the internet. Everything you send and receive travels through that tunnel, completely unreadable to anyone else on the same café WiFi. It is the single most effective thing you can do for public WiFi safety on your Mac in Lagos, or anywhere else.
I use and recommend Proton VPN. It is Swiss-based, which means it operates under some of the strongest privacy laws in the world. It is open source — the code is publicly audited. The free tier is genuinely useful. The paid plan is reasonable. Unlike many VPN services that quietly sell your browsing data to advertising networks, Proton's entire business model is built on privacy. They cannot sell what they do not have.
Install Proton VPN on your Mac, iPhone and iPad
Set it to connect automatically on unknown networks
Turn it on before you open your browser — not after
Keep it running for the entire session, not just for sensitive tasks
The habit to build: VPN on before the flat white arrives. Not halfway through it.
Use Your iPhone as a Hotspot Instead
For anything genuinely sensitive — banking, client contracts, anything you would not want intercepted — skip the café WiFi entirely and use your iPhone as a personal hotspot. Your phone's mobile data connection is significantly harder to intercept than a shared WiFi network, and in Lagos the 4G and 5G coverage from NOS, MEO and Vodafone is excellent.
On your iPhone: Settings → Personal Hotspot → Allow Others to Join. Connect your Mac to it as you would any WiFi network. Your phone becomes a private, encrypted gateway to the internet that belongs to you alone.
The data cost is minimal for occasional use. The peace of mind is considerable.
A real situation — Lagos, 2025
A client came to me after noticing unusual activity on a cloud storage account. He had been working from various cafés around Lagos for several weeks without a VPN, syncing files constantly. Nothing was stolen in any obvious sense. But an old app he used had been transmitting session data in the clear, and someone on the same network had picked it up.
The fix was straightforward: Proton VPN installed, the old app updated, and his Mac audited for any other applications behaving similarly. Fifteen minutes of work. The incident itself — logging calls, checking what had been accessed, updating passwords — took most of an afternoon.
The VPN would have prevented it entirely.
Check Your Mac Is Not Advertising Itself
By default, your Mac may be discoverable on local networks — sharing services, AirDrop set to "Everyone", Bluetooth left open. On a home network this is harmless. On a café WiFi in Lagos with thirty strangers, it is less ideal.
Go to System Settings → General → Sharing and review what is switched on. Turn off anything you do not actively need. For AirDrop, set it to "Contacts Only" rather than "Everyone". These are small changes that meaningfully reduce your exposure on public networks.
Firewall: turn on — System Settings → Network → Firewall
Keep macOS and Apps Up to Date
Every macOS update Apple releases contains security patches — fixes for vulnerabilities that, if left unpatched, could be exploited on a shared network. The same applies to every app on your Mac. Outdated software is the most common reason a well-intentioned person ends up with a compromised machine.
Turn on automatic updates: System Settings → General → Software Update → Automatic updates: On. Let Apple handle it in the background. It costs nothing and closes doors you did not know were open.
Encrypt Your Drive. While You Are At It.
If you are working from cafés, your Mac is leaving the house regularly. Bags get left on chairs. Theft, though rare in Lagos, is not zero. FileVault — Apple's built-in full-disk encryption — means that if your Mac is ever taken, it is an expensive paperweight to whoever has it. Your data stays yours.
System Settings → Privacy & Security → FileVault → Turn On. It encrypts in the background while you work and has no noticeable performance impact on modern Macs.
The Complete Café Checklist Before You Open Your Mac
VPN connected before you do anything else
For banking or sensitive work: use iPhone hotspot instead of café WiFi
AirDrop set to Contacts Only
Firewall on
macOS and all apps up to date
FileVault enabled on your drive
Lock screen set to activate after 2 minutes of inactivity
None of this takes more than a few minutes to set up once. After that it is invisible — running in the background while you enjoy the view.
The Best Cafés to Work From in Lagos
While we are here — a few places worth knowing. The historic old town has several spots with reliable WiFi and enough ambient noise to make you feel productive without being distracted. The marina area is good for a long afternoon session with a view. For focused morning work, the quieter streets away from the tourist centre tend to be more consistent for connection speeds.
Whatever you choose, bring your VPN. The coffee is excellent. Your data should stay that way too.
Not sure if your Mac is set up securely?
I check this for clients in Lagos all the time — VPN configuration, Sharing settings, FileVault, software updates. One session, in person or remote, and your Mac is properly secured for working anywhere in the Algarve. Same day, no fuss.
