Not OP but I use Monzo and they have a very silmilar from to this. You have to enter an email address for account recovery and they send you a "magic link" that opens the app and logs you in, if you ever get logged out.

You then have to record a video selfie saying something like "I am NAME and I want to recover my account" and then send a pic of an ID. Same process (the selfie+ID part) for if you want to display your card PIN reminder.
