Reset the password with the Cartão de Cidadão or Chave Móvel Digital (immediate)Do you have a Cartão de Cidadão with PIN codes or an active Chave Móvel Digital (digital mobile key)? → Yes

Under “Iniciar sessão” choose “Recuperar senha de acesso” and then “Escolher senha”: you are sent to Autenticação.gov, authenticate with the Cartão de Cidadão or the Chave Móvel Digital and set a new password straight away.

Official leaflet “Acesso ao Portal das Finanças – Autenticação e Senhas”, section 4: with CC or CMD you “poderá redefinir a sua Senha, o seu Código de Acesso Telefónico e a sua Pergunta e Resposta de Segurança”.

Portal das Finanças: log in › recover password ↗

  • Cartão de Cidadão: you need the card reader and the authentication PIN.
  • Chave Móvel Digital: you need the linked mobile phone and the PIN; you receive a code by SMS.
  • Choose a new password and, if you wish, update the security question and the telephone access code too.

Next step: Go to the Portal das Finanças and use “Recuperar senha de acesso” › “Escolher senha”.

Code by SMS (immediate)Do you have a Cartão de Cidadão with PIN codes or an active Chave Móvel Digital (digital mobile key)? → No; Do you remember the security question and answer you chose when registering? → Yes; Is your mobile number confirmed on the Portal das Finanças? → Yes

With the security question and a confirmed mobile number you can choose “Código por SMS”: you receive a 6-digit code, have 5 minutes to enter it and set the new password at once.

Official FAQ 5470: “Por SMS, após selecionar a opção “Código por SMS” … recebe no seu telemóvel por SMS um código de 6 dígitos. Tem 5 minutos para o digitar”.

Portal das Finanças: recover password ↗

  • Have the exact answer to your security question.
  • Have the confirmed mobile phone with you; the Portal shows the last 3 digits to confirm.
  • If you prefer, the alternative is “por carta” (by letter): the old password is cancelled and the new one reaches your tax address in about 5 working days.

Next step: On the Portal, “Recuperar senha” › security question › “Código por SMS”.

New password by letter (about 5 working days)Do you have a Cartão de Cidadão with PIN codes or an active Chave Móvel Digital (digital mobile key)? → No; Do you remember the security question and answer you chose when registering? → Yes; Is your mobile number confirmed on the Portal das Finanças? → No, or I don’t know

With the security question but no confirmed mobile number, the Portal cancels the old password and posts a new one to your tax address (domicílio fiscal), on average within 5 working days.

Official FAQ 5470 and the passwords leaflet: the password “será emitida automaticamente e enviada obrigatoriamente através dos CTT”, average 5 working days; it cannot be sent by e-mail or to another address.

Portal das Finanças: recover password ↗

  • Check that your tax address is up to date: the letter only goes there.
  • If you have an urgent obligation, you can request a “senha na hora” (on-the-spot password) at a Serviço de Finanças (by appointment).
  • To know whether the letter was sent, the CAT answers on 217 206 707.

Uncertain: If your tax address is out of date, changing it is a separate procedure (Cartão de Cidadão or Serviço de Finanças) before the request.

Next step: Request the new password on the Portal and wait for the letter; for urgent cases, book an appointment for a “senha na hora”.

Cancellation by e-mail and new registration (letter in about 5 working days)Do you have a Cartão de Cidadão with PIN codes or an active Chave Móvel Digital (digital mobile key)? → No; Do you remember the security question and answer you chose when registering? → No; Do you know which e-mail is registered in your AT details, and do you still have access to it? → Yes

Without a security question, CC or CMD, send a cancellation request from the e-mail registered with the AT to portal-senhas@at.gov.pt; after confirmation, register again and receive the password by letter.

Official page “Recuperar a senha de acesso”: subject “Cancelamento de senha NIF (your NIF)”; body with NIF, full name and tax address; attach a copy of your identity document and a signed request; then “Registar-se” on the Portal.

Official instructions for cancellation by e-mail ↗

  • Send it from the e-mail registered with the AT.
  • Subject: “Cancelamento de senha NIF” followed by your NIF.
  • In the body: NIF, full name and tax address.
  • Attach a scanned copy of your identity document and a signed request asking for the cancellation.
  • After the e-mail confirmation, use “Registar-se” on the Portal; the password reaches your tax address by post in about 5 working days.

Uncertain: The AT does not state a deadline for confirming the cancellation.

Next step: Send the cancellation e-mail and, after confirmation, register again.

Update the e-mail at a Serviço de Finanças (by appointment)Do you have a Cartão de Cidadão with PIN codes or an active Chave Móvel Digital (digital mobile key)? → No; Do you remember the security question and answer you chose when registering? → No; Do you know which e-mail is registered in your AT details, and do you still have access to it? → No

Without a security question, CC/CMD or a known registered e-mail, the AT says to request the e-mail update at a Serviço de Finanças; then follow the cancellation by e-mail and the new registration. For urgent obligations there is the “senha na hora” at the counter.

Official page “Recuperar a senha de acesso”, point 3: “Solicite junto de um Serviço de Finanças a atualização do endereço de e-mail”; note: “Se tiver uma obrigação fiscal urgente para cumprir, pode pedir a emissão de uma “senha na hora” no Serviço de Finanças”.

Book an in-person appointment (Portal das Finanças) ↗

  • In-person service is by appointment; without a password, book through the CAT (217 206 707) or ask someone with access to help.
  • Bring your identity document.
  • With the e-mail updated, make the cancellation request by e-mail and register again.

Uncertain: The documents accepted to prove identity at the counter are not listed on the official page consulted.

Next step: Book an appointment to update the e-mail (or to request a “senha na hora” if urgent).
