GAM Local Authentication TypeOfficial Content

In Local Authentication Type user credentials are stored in "User" GeneXus Access Manager table.

GAM does not store the password of the user, but it stores a hash of it. A hash is an algorithm such that given a string, produces always the same resulting string, and given the resulting string you cannot get the original.

The hash is obtained from a unique key for each user and an algorithm named SHA-512 (Secure Hash Algorithm).

This means that when you retrieve GAM Users from the repository, the password property will always have an empty value.
