Manual:Resetting passwords/zh

在一些情况下，用户可能需要重置其密码. 例如，用户忘记了自己的密码，或是遇到某种可能会泄露其密码的安全漏洞. 大多数情况下，可以使用“通过邮件获得新密码”来重置密码.

对于忘记用户名或是无法查看邮箱的用户，可能需要管理员或系统管理员进行一些额外操作.

使用 Special:UserLogin
如果您知道自己账户的名称，则可以使用登陆界面上的“忘记密码”功能. 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  table of the MediaWiki database to find the associated username. For example, to find the username for, run the following query:

Use the changePassword.php maintenance script
The maintenance script allows system administrators to change the password for an account. For complete instructions see. If you are already familiar with maintenance scripts, run the following command:

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.

Use Special:PasswordReset
Special:PasswordReset allows accounts with the 'editmyprivateinfo' permission to reset account passwords for the local installation of MediaWiki.

To use:


 * 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  field inside the   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  in. 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.
