  2. Log in with your online banking ID or mobile certificate at
  3. After logging in, select “MFA reset” and confirm.
  4. Wait a while for the information to update between the systems (max. 10 min) and continue by logging into M365 at and follow the instructions given.
    • Notice! Log in with your e-mail address (short username is not enough).
