If we have bank device at the log-in stage to input password, would this mean Bitwarden cannot be used? and in this case, what are your recommendations?
Not sure what you mean by “bank device.” If your device provides your entire one-time password, then you can’t use a password manager to enter it at login.
The device we have is a key-fob type device that generates a one-time use, six-digit code. That code that is entered at the end of our login password. We use a password manager to enter our ID and partial password, then the complete the password by entering the device-generated code.
