My Bank forces it’s clients to change their Passwords every 6 months and a Password that has been used in past 2 years can’t be used as a ‘New Password’.
Under these circumstances no App can be used except brain memory or saving the latest Password in a password protected pdf document.
The bank does allow creation of a new Password through a OTP (one time password) a six digit random number sent by the bank to Registered Mobile Number if the client.
