Password management (PM) tools are products that provide users with the means to reset their own passwords after an account lockout or when they forget their passwords. PM tools can also synchronize passwords for users across multiple systems, allowing users to access multiple applications with the same password.
Gartner defines user authentication as the journey-time process that provides credence in a claim to an identity established for a person for access to digital assets. User authentication is delivered by some combination of (a) an authenticator, (b) signals evaluation and (c) an authentication decision point, which may be from different vendors.
