Within Wikimedia projects, a bureaucrat is a user who has the technical ability to:
- Promote other users to administrator or bureaucrat;
- Grant and revoke a user's bot flag;
- Add and remove users from custom local groups created by local consensus like account creator, deleter, etc;
- Rename a user;
- Remove a user administrator and/or bureaucrat flags on some projects listed below.
Stewards fulfill these roles on wikis without bureaucrats using the requests for permissions page. A small community generally doesn't require a local bureaucrat, because stewards can easily handle the low traffic of requests from that wiki with little delay; generally a user with this access is not needed until several local administrators are present. Other positions may be subject to global policies like the Checkuser policy and the Oversight policy, which define minimum community requirements. The default configuration of the MediaWiki software permits bureaucrats with access to Special:UserRights to add and remove users from all user groups. On Wikimedia Foundation wikis only stewards have full access to Special:UserRights, while bureaucrats can add/remove only a subset of rights.
Promoting users and bots 
- See also: a tutorial
If you are a bureaucrat, to give or remove another user administrator, bureaucrat or bot access (or any other access), go to Special:UserRights on the wiki where you are a bureaucrat. There is a link to this on the list of special pages.
You will see the following form:
Type the user's name into the box, and enter a reason for the change. Choose the rights you wish to assign/remove to the user by ticking/unticking the relevant boxes. Note that if the user group has an asterisk (*) next to it, you will not be able to remove it yourself. When you are done, press the Save user groups button.
The user will gain their access immediately and the action will be recorded at the User rights log.
If you make a mistake and need to remove an access level which you cannot remove, contact a steward.
Renaming users 
- See also: a tutorial
The above is the current interface for renaming users. Before you rename a user, you must visit Special:RenameUser. It is fairly self-explanatory. One must simply key in the current name, the target name, and the reason for the change. The box ticked to move user and user talk pages is ticked by default, as this is the most frequent scenario.
Removing access 
Below is a list of public wikis, where bureaucrats can remove sysop and bureaucrat access.
