Pow v1.0.17 Pow.Store.CredentialsCache View Source
Default module for credentials session storage.
A key (session id) is used to store, fetch, or delete credentials. The
credentials are expected to take the form of
{credentials, session_metadata}
, where session metadata is data exclusive
to the session id.
This module also adds two utility methods:
users/2
- to list all current userssessions/2
- to list all current sessions
