Why am I asked for a code each time I log in to my digital bank account?

The request to enter a code upon login is due to multi-factor authentication, a security method that requires more than one form of identification to log into an account. We use multi-factor authentication to help keep your account safe.

However, if you are using a personal device that is not shared with anyone else, you could choose to register your device when you login. When you login from a registered device, you will not be required to enter a code.
