and KDE open source desktops. In addition, web browser developers have added similar functionality to all of the major browsers. Although, if the user's system is corrupted, stolen or compromised, they can also lose access to sites where they rely on the password store or recovery features to remember their login data. Password management software such as KeePass and Password Safe can help mitigate the problem of password fatigue by storing passwords in a database encrypted with a single password. However, this presents problems similar to that of single sign-on in that losing the single password prevents access to all the other passwords while someone else gaining it will have access to them. Password recovery - The majority of password-protected web services provide a password recovery feature that will allow users to recover their passwords via the email address (or other information) tied to that account. However, this system has itself become a target of social engineering attacks by criminals. These criminals obtain enough information about the target to impersonate them and request a reset email, which is then redirected through other means to an account under the attacker's control, enabling the attacker to hijack the account. Passwordless authentication - One solution to eliminate password fatigue is to get rid of passwords entirely. Passwordless authentication services such as Okta, Transmit Security and Secret Double Octopus replace passwords with alternative verification methods such as biometric authentication or security tokens. Unlike SSO or password management software, passwordless authentication does not require a user to create or remember a password at any point.
