14. Users and Authentication > More Options
More Options
A complete application would support many more tasks around authentication. A few of the most notable include:
-
Logging in through Twitter, Facebook, and others (the Railscasts cover this)
-
An interface for managing users and privileges
-
Letting users stay logged into their account on a given browser
-
Finer-grained permissions for different categories of users
-
Mechanisms that let users reset their passwords
-
Email address verification
-
Detailed account settings that let users set preferences
All of these things, however, are projects with details that vary
widely across different applications. The OmniAuth gem supports some of
these options, such as connecting the password system to email, but most
of this is work that’s very dependent on what precisely you want to build.
The users model is a model like any other: you can extend it, connect
tables to it, and build whatever system you’d like behind your
application. The OmniAuth gem gives you
a foundation, and you can build whatever you need on top of it.
