Password managers are not without security flaws, as seen in a recent high-profile breach. The database storing all the user's passwords is a very attractive target for hackers. Spectre is a new password manager that aims to solve this problem by using a unique password generation and management approach.
It sounds like a cool concept, but I can’t see anyone migrating to this service since there is no logical way to import your current passwords.
Any “password” that cannot be revoked is a bad password.
This is also why biometrics are bad. You can’t replace your fingers, eyes, etc… These are good usernames.
