WP:SULWP:SUL

Unified login or SUL (single user login) is a mechanism which allows users to use a single global login on all public Wikimedia Foundation 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 request a rename of your global account, see Special:GlobalRenameRequest
To view your global account's contributions, see Special:CentralAuth
To request your global account to be vanished, see Special:GlobalVanishRequest
