Como encontrar sua senha de Wi-Fi

• Você precisa de pelo menos um dispositivo já conectado à rede, ou acesso físico ao roteador.
• Na maioria das plataformas, você precisará de uma senha de administrador ou PIN do dispositivo para revelar uma senha de Wi-Fi salva; esta é uma medida de segurança, não um bug.
• Depois de se reconectar, execute nosso Teste de Rede para confirmar que a conexão está realmente funcionando corretamente, não apenas conectada.

1. Right-click the Wi-Fi icon in the taskbar and choose "Network & internet settings".
2. Click "Advanced network settings" > "More network adapter options", or go to Settings > Network & internet > Advanced network settings.
3. Alternatively, open Control Panel > Network and Sharing Center > click your Wi-Fi network name > Wireless Properties > Security tab.
4. Marque a caixa "Mostrar caracteres" para revelar a senha em texto simples.

If Control Panel feels dated, you can also open Command Prompt as administrator and run netsh wlan show profile "NETWORK-NAME" key=clear, então procure por "Conteúdo da Chave" na saída.

1. Abra o Spotlight (Cmd+Espaço) e procure por "Acesso às Chaves".
2. Na barra de pesquisa do Acesso às Chaves, digite o nome da sua rede Wi-Fi.
3. Clique duas vezes na entrada correspondente e, em seguida, marque "Mostrar senha".
4. Digite a senha de login do seu Mac quando solicitado, isso confirma que é realmente você.

1. Open Settings > Network & internet > Internet (or Wi-Fi).
2. Toque no ícone de engrenagem ao lado da rede à qual você está conectado.
3. Toque em "Compartilhar", o que gera um código QR e, em muitas versões do Android, mostra a senha como texto abaixo dele.
4. Alguns fabricantes ocultam a senha em texto simples atrás de uma solicitação de impressão digital ou PIN primeiro, o que é esperado.

O iPhone não mostra senhas de Wi-Fi salvas diretamente nas Configurações, mas há duas maneiras confiáveis de obter uma:

Se nenhum dispositivo estiver conectado, vá à fonte.

1. Verifique o adesivo no próprio roteador, a maioria tem um nome de rede e senha padrão impressos na parte inferior ou traseira.
2. Se tiver sido alterado do padrão, conecte um computador ao roteador com um cabo Ethernet e abra sua página de administração, geralmente em 192.168.0.1 ou 192.168.1.1 em um navegador.
3. Faça login com as credenciais de administrador do roteador (também frequentemente no adesivo, separadas da senha do Wi-Fi) e procure em configurações de Wireless ou Wi-Fi.
4. Use o nosso Public IP & Location ferramenta se você não tem certeza em qual rede está antes de mexer nas configurações do roteador.

• Como último recurso, você pode redefinir o roteador para as configurações de fábrica usando o pequeno botão de reset, geralmente pressionado por 10 segundos. Isso restaura a senha padrão impressa no adesivo, mas também apaga quaisquer configurações personalizadas.
• Após uma redefinição de fábrica, altere a senha para algo novo e atualize-a em todos os seus dispositivos de uma vez.
• Se o seu provedor de internet gerencia o roteador, o aplicativo ou portal da conta deles geralmente mostra as credenciais de Wi-Fi atuais sem a necessidade de acesso físico.

People often reach for the router reset button first, and it is almost always the worst option. A factory reset wipes the network name, the password, port forwarding rules, guest network settings, parental controls and any custom DNS configuration, then forces you to reconnect every device in the house. Since any device already connected is storing the password locally, recovery is nearly always possible without touching the router at all.

Operating systems protect stored passwords behind an administrator prompt rather than hiding them entirely, because the intention is to stop a passing stranger reading credentials off an unlocked screen, not to stop the owner. If you can authenticate as the machine's owner, you can see the password. That is the principle behind every method in this guide.

Pick the approach that matches what you have access to, rather than working through every option.

• A connected Windows PC and administrator rights: use the network properties dialog or the command line, this is the fastest route and shows plain text immediately.
• A connected Mac: Keychain Access, which also covers passwords synced from an iPhone through iCloud Keychain.
• A connected Android phone: the share option, which produces a QR code and often the password beneath it.
• Only an iPhone connected: use the password sharing prompt to bring a new device online, or read it through a Mac sharing the same iCloud Keychain.
• Nothing connected at all: the router sticker first, then the router admin page over an Ethernet cable.

If a QR code is all you can get, that is usually enough. Point the new device's camera at it and most modern phones will offer to join the network directly, no typing required.

Router admin pages present several credentials that people routinely confuse. The Wi-Fi password, sometimes labelled the network key, pre-shared key or WPA key, is what devices use to join. The admin password protects the router settings page itself. On many routers both are printed on the sticker but they are different strings, and typing one where the other belongs produces a confusing failure.

• SSID is simply the network name you see in the list of available networks.
• WPA2 or WPA3 is the security standard, newer is better, and mixed mode keeps older devices working.
• Some routers run separate 2.4GHz and 5GHz networks with different names but usually the same password.
• A guest network has its own password entirely and often blocks access to printers and shared drives.

If you do end up changing the password, choose something you will not have to recover again. Length beats complexity for Wi-Fi keys, since they are typed rarely and stored permanently. Three or four unrelated words joined together is both stronger and far easier to read aloud to a guest than a random string of symbols.

1. Use at least sixteen characters, and avoid the street address or family names that a neighbour could guess.
2. Store it in a password manager under the network name, so future recovery takes seconds.
3. Write it on a card kept near the router for guests rather than sharing your main credentials verbally.
4. Enable WPA3 if every device supports it, and keep WPA2 as a fallback if older equipment needs it.
5. Change the router admin password too, the default is published online for every common model.

After changing anything, reconnect one device and confirm the connection genuinely works rather than just showing connected. A speed and latency check catches the case where the network joined successfully but the internet connection behind it is down for an unrelated reason.

The reason this problem repeats is that nobody writes the password down anywhere durable. Five minutes of record keeping now removes the whole task permanently, and it also makes the network easier to hand over if someone else ever needs to manage it.

• Store the network name, wireless key, router admin address and admin password together in a password manager entry.
• Photograph the router sticker and keep the image in the same entry, defaults are useful after any reset.
• Note the router model and firmware version, which speeds up any future support conversation considerably.
• Keep a printed card near the router with the guest network details only, so visitors never need your main key.
• Repeat the record after any password change, an out of date note is worse than none at all.

Once the record exists, verify it. Join a device that was not previously connected using only the written details, then confirm the connection genuinely reaches the internet rather than simply showing connected. A quick speed and latency check settles that in seconds and proves the note is accurate.
