The BankID app replaces the code device, as long as the customer has BankID from a bank that offers the app. The user chooses ordinary BankID when selecting the login method, before approving the login in the app and entering the personal password. The app is a so-called "Silent-OTP" where the user can approve a login or a signing through the phone instead of entering the code from a physical code device. Brukersted with BankID does not need to take any additional actions to open the BankID-app if they use BankID on web today.
