Authentication is the process by which a user establishes his identity to a system or application.
Broadly, users must supply their credentials to sign into a system, which may fall into three categories:
- Something the user knows -- i.e., a secret, such as a password, PIN or the answer to a security question.
- Something the user has, such as a one time password token, smart card or mobile phone.
- Something the user is, meaning a biometric measurement of the user -- his voice print, finger print, vein pattern scan, iris or retina scan or some behaviour, such as his typing cadence.
Hitachi ID Password Manager is a solution that helps users to more effectively manage their already-existing credentials and resolve problems such as forgotten passwords or PINs in a self-service fashion.
