Unified login or SUL (single user login) is a mechanism which allows users to use a single global login on most of the Wikimedia Foundation's projects. This allows users to maintain a consistent identity throughout Wikimedia and work on different projects without having to sign up and log in to each project individually.
- For information about unified login, see m:Help:Unified login
- To create an SUL for your accounts, see Special:MergeAccount
- To request a rename in connection with SUL, see Wikipedia:Changing username
- To view your SUL account's contributions, see toolserver.org/~quentinv57/sulinfo/ or Special:CentralAuth
