I think offline hardware password managers are the most secure.
Including offline backup.
For this, I developed Authorizer to use your old Android phone as your password manager. It can type the password over USB on your target device.
Supports OTP.
Smartcard and WebAuthn support are on the roadmap.
Doing also a lot of modernization on the next weeks.
