Strong passwords and two-step verification

Protect each account with a unique password and a second verification step.

One account, one password

Use a long, unique password for each service. A trusted password manager can create and store different passwords; protect it with a strong passphrase you can remember.

Add a second barrier

Turn on two-step verification (2FA) for important accounts, especially email and banking.
When available, use an authenticator app or security key. Keep recovery codes somewhere safe, separate from your device.
Never share access codes, even with someone claiming to be from your bank or technical support.

Example: if a password is exposed, change it on that account and on any other account where you reused it. See also the Bank of Portugal’s guidance.
