PIN is short for personal identification number. It is a short, numeric form of a password. Since PINs are normally both short and numeric, they are much less secure (i.e., much easier to guess) than passwords. This means that they should rarely be used alone, but rather are often combined with other types of authentication factors in a multi-factor authentication arrangement.

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.
