There are any number of situations where a user may need to reset their password. Typically, people either forget their password or experience some kind of security breach that may have disclosed their password. For most situations, they can reset their own password using "Email new password".
In situations that are complicated by the user forgetting their account name or losing access to their email, additional measures may need to be taken by an administrator or system administrator.
If you know the username for an account, you can use the "Email new password" feature on the Special:UserLogin page. To use the feature, visit the Special:UserLogin page for the relevant wiki, fill in the Username field of the form and press the ”Email new password" button. A temporary password, along with instructions on how to reset the account's password, will be sent to the email address associated with the username.
Finding the username for a given email address
If you know the email address for a user, but not their username, query the
user table of the MediaWiki database to find the associated username.
For example, to find the username for
email@example.com, run the following query:
SELECT user_name FROM user WHERE user_email = 'firstname.lastname@example.org';
Use the changePassword.php maintenance script
The changePassword.php maintenance script allows system administrators to change the password for an account. For complete instructions see changePassword.php. If you are already familiar with maintenance scripts, run the following command:
# set the password for username 'example' to 'newpassword' sudo php changePassword.php --user=example --password=newpassword
Caution: System administrators should not know the unencrypted password for user accounts. A user may use the same password over many different sites. If one of their accounts that uses the same password is compromised, then suspicion can be thrown on the administrator. It is better to use "Email new password" to force the user to reset the password for their own account or to set a temporary password the user changes directly afterwards.
Special:PasswordReset allows accounts with the 'editmyprivateinfo' permission to reset account passwords for the local installation of MediaWiki.
- Type username you want to reset in box provided and click "Reset password"
- An automatically generated password will be emailed to the user
For automatically inserting the username in links, use
Direct database modification
To reset a password you can change the value of the
user_password field inside the
user table in your database.
However, it's generally far easier and safer to use "Email new password" or use the changePassword.php script. You should only use direct DB modification as a last resort, as its very easy to accidentally mess up your wiki. Always backup your database before doing any manual modification. The following only works when using MediaWiki's default authentication provider. If you are using an extension that modifies the authentication process (Like LDAPAuth), the following may not work.
The format you see in the user table will depend on
$wgPasswordDefault in LocalSettings.php. However if you use a different format, it will automatically be changed to the correct format the next time the user logs in. Thus for this guide, we show how to manually set the "B" format. This format is very easy to set from an SQL query. It is not the default format as it is weaker than pbkdf2, however that's ok as the user_password field will be upgraded to the correct format the next time the user logs in.
- MySQL salted (1234 is the salt. You can replace it with any number as long as both places the number is used are the same)
UPDATE `user` SET user_password = CONCAT(':B:1234:', MD5(CONCAT('1234-', MD5('somepass')))) WHERE user_name = 'someuser';
- PostgreSQL salted
update mwuser SET user_password = text(':B:1234:') || MD5(text('1234-') || MD5('somepass')) WHERE user_name = 'someuser';
Also restarting Apache and clearing your browser cache might help.
You can copy the known password from one account to another:
SELECT user_id, user_name, user_password FROM user; +---------+-----------+----------------------------------------------+ | user_id | user_name | user_password | +---------+-----------+----------------------------------------------+ | 1 | User1 | :B:1d8f41af:1ba8866d9c43d30b7bc037db03a067de | | 2 | User2 | :B:ee53710f:4291b056175513a5602d48eaeb79705c | +---------+-----------+----------------------------------------------+ UPDATE user SET user_password = ':B:ee53710f:4291b056175513a5602d48eaeb79705c' WHERE user_id = 1;
