Password managers are helpful in creating and storing complex passwords, but most store those passwords in an encrypted vault. Password managers use a combination of information from different sources to reconstruct a password. Amnesia is a password manager that uses a secret, 256-bit value that is stored in a table on a user’s phone. The idea of a secret token sent from the phone could be used to augment one-time passcodes sent by SMS, used by many two-factor authentication schemes. The Amnesia project isn’t perfect, but it eliminates the weakness of password vaults.”]
