I understand there are a few other controls, like 2FA, for making transactions in many bank account websites, while only users required for username and password to access the account.
I noticed that I can save my password in my LastPass password manager while in my other bank account they disabled it somehow. Working for a financial company myself, it made me consider creating this kind of protection: an option of disabling the option for users to save their passwords to their password managers like LastPass.
It will be very easy to implement this kind of client-side encryption solution but I am wondering why would these banks do this "extra" line of security protection.
