Your bank lets you use letters? Mine just numbers. The registration allowed 10 numbers but the login does not allowed more than 8… At least they block the account after 3 incorrect guess and make you ask for a reset in person. So I had to go twice in a day… and the teller lady asked why I don’t use 4 digits like a normal person… Sill beter than the other bank which sends the password back in plain text email after registration in 2019
