Issues with Mobile BankID or Card PIN

Forgotten BankID Security Code If you have forgotten your Mobile BankID security code, you must order a completely new Mobile BankID through the online bank or app.

Blocked BankID If you suspect an unauthorized person has gained access to your device, block your BankID immediately. You can do this via the “Get and manage BankID” section in the online bank, or by calling our Blocking Service at 08-402 57 10.

Blocked Card PIN If you enter the wrong PIN code three times in a row when logging in with a card reader, the PIN is blocked for reader use. You can easily unlock it by making a standard chip and PIN purchase in a physical store or by withdrawing cash at an ATM.
