Help pages Unified login
Unified login is a mechanism which allows users to use a single login across the majority of the Wikimedia Foundation's projects. This allows users to maintain a consistent identity throughout Wikimedia, following a single sign-up. Other advantages of this mechanism include the removal of the threat that impersonation poses and the ability to visit many projects without having to go through the labors of logging in everywhere. Users can create a unified login by visiting Special:MergeAccount on a project where they already have an account, and following the prompts.

About unified login[edit]

What it is[edit]

The Wikimedia Foundation operates a family of editable online resource communities. Users were traditionally required to create a separate login account on each of these projects, in each language they appear in. This adds an extra burden for contributors becoming involved in multiple projects, particularly as multimedia integration with Wikimedia Commons becomes more essential.

The unified login system combines the user accounts for all of these projects. The greatest advantages are single sign-up (you don't have to create your account again on each new project you get involved with; your account is automatically created at each additional Wikimedia project the first time you log on to that wiki with your existing username and password, or the first time you visit it while logged on to a wiki where you already have an account) and consistent identity (your username now always means you; no one else can take your name on another project).

How to unify your accounts[edit]

Currently, all new accounts are unified by default, and older accounts can be manually unified by their users. To do so, go to Special:MergeAccount on a wiki where you already have an account. The wiki where the account of that username has the most contributions will become the home wiki,[1] and its email address and password will be exported to all other accounts.

At Special:MergeAccount, you will be asked to enter your password for verification. Then, any wikis with the same authenticated e-mail address and password as the home wiki will be unified. You can enter the passwords of additional accounts if any are listed.

When you are finished, or if you have already unified your account, you will receive the message "Login unification complete!" You will be able to log in at any public Wikimedia wiki with your home wiki username and password, unless an existing non-unified account has the same username.

If your account is blocked on your home wiki, the unification process will not proceed.

What it changes[edit]

Registering a username on any Wikimedia wiki automatically reserves that name on all the others; this means different users can no longer register the same account on different wikis. Users only need to set and confirm their email address in one account. Changing the password in any wiki changes it in all wikis accordingly. Special:UserLogin now logs the user in to every unified wiki simultaneously, and navigating away from the login page before it is fully loaded may result in incomplete login (i.e. users may not log in to all wikis successfully).

Additional wikis will be added to the user's login the first time they are visited. For example, a regular user at Commons and German Wikipedia will not automatically login to English Wikibooks, but if that user visits English Wikibooks once while logged in, they will then login to English Wikibooks every time (to see which wikis you log in to, see Special:CentralAuth).

What it doesn't change[edit]

  • Some things are still local:
    • User rights are mostly local, which means that administrators will not have administrator access everywhere. Global groups such as global rollback, global sysop, global edit-interface and global IP block exemption can now be requested at Steward requests/Global permissions. Global rollback and global sysop are only granted to users who are demonstrably active on other wikis aside from their home wiki.
    • User preferences are local, although the email address only needs to be set and confirmed in one place. You can continue to have different preferences on different sites.
    • Notification when you receive a new message is still local; you will only see the "new messages" box for the site you're looking at. This may change in the future.
  • Users can still have differently named accounts on two sites; however, these accounts will not be linked for unified login.
  • The unified login system is only available for the Wikimedia Foundation wikis; sites which run on the MediaWiki software but are not operated by the Foundation will continue to have separate account systems, even if they installed Extension:CentralAuth, which is responsible for the unified login system.

Conflict resolution[edit]

The system will automatically merge identically named accounts if they have the same authenticated email address, or the user can correctly provide their password.

Because registration has for a long time been separate for each wiki, there are many user names that belong to different people on different projects. The new system only allows one user per name, so there are some cases where accounts will need to be renamed. This must be done manually by a bureaucrat or stewards (see Steward requests/Usurpation).

Users may search for collisions before merging by using the SUL collision detector.

Bureaucrats can be found at the page Special:ListUsers/bureaucrat on each wiki, for example, en:Special:ListUsers/bureaucrat.

Stewards can view global username data and manually unmerge accounts using Special:CentralAuth.

History[edit]

Early discussions can be seen on the Single login page.

Brion Vibber is committed to this project. He discussed how this might work in the December 2005 Berlin roundup, uploaded implementation notes to the code base in April 2006, and it was the subject of a presentation at Wikimania 2006.

Brion announced a successful migration test in November 2006. Data collection took two hours and automatic merging took five hours. 4,457,075 primary accounts were confirmed, with 578,128 secondary accounts merged automatically based on matching email addresses or by cannibalizing unused accounts. 134,242 secondary accounts will need to be merged with user interaction (71,741 unique user names have accounts left unmerged).

Unified login was implemented for administrators only in March 2008, and Steward requests/Usurpation was created to perform conflict resolution. It was opened up to all users on May 27, 2008.

Frequently asked questions[edit]

Can I be renamed after unification?[edit]

Yes, but you have to request your account renaming on all wikis separately.

Can I merge different usernames?[edit]

No, but this might be possible in future versions.[2]

Note that usernames on most individual projects can preemptively be renamed.

Someone is using my name on another wiki, how can I get that account?[edit]

First, note that the existence of the other account does not necessarily stop you from getting the global name. However, if an account with your chosen name which is not controlled by you has more edits, or certain group membership such as sysop or bureaucrat (check here), you may not be the one with the superior claim on this username. If this is the case, you will probably have to ask them to rename, or you may have to rename yourself.

When you merge your account, it will tell you that the merge is incomplete, but it will also create the global account for you at that time. You will be able to use the global account on all wikis except for the ones where the named account is not under your control.

If you want to usurp an account on another wiki, you should make a request to a bureaucrat on the problem wiki. Subject to local policy, the bureaucrat may be able to rename the target account. If there's no bureaucrat on the wiki you should ask a steward to usurp this account.

Will I have autoconfirmed status on other wikis?[edit]

No. You will have to wait the appropriate amount of time after first logging into each particular wiki, before getting autoconfirmed status.

Can I merge accounts from restricted-account-creation wikis?[edit]

No. This is for security reasons. If the wiki has account creation restricted then it is not able to be merged at this time.
