If someone else than you has your log-in information, it's possible for them to log in using your user. To stop them from doing so, you can disable your Altinn code letter and/or password.
The ID-porten log-in methods has their own disabling service.
To disable the Altinn alternative log-in methods, choose Log in → Proceed to alternative log-in methods and click Disable single-use codes / password.
- By deactivating single-use codes (code letter), the code letter will not work, and you will need to order a new code letter to use this log-in method again.
- By deactivating your password (SMS-code or password only), you will be unable to use the password when logging in. If you use another log-in method, you can enter a new password under Profile → Advanced settings → Login information.
