My phone often has issues recognising my thumb print and I’ve been locked out of the Monzo app a few times at rather inconvenient moments now due to that. I don’t like to turn it off though as then anyone with access to my phone could access my Monzo account.
It would be much better if I could unlock Monzo with a password if the thumbprint ID failed, ideally a different password to the one I use to unlock my phone so if it was stolen and that password was guessed the thief couldn’t access my bank account.
