Hi there,
I would advise to use a database and store the credentials when the user connects on your website.
Just create a TwitterCredentials table that you link to the UserCredentials of your website.
When the user connects with his user credentials, use the TwitterCredentials to do your operations.
Verify that the credentials are valid each time the user creates a new session because they could have been revoked since the last session.
