상세

Default password type to use when hashing user passwords. The choices are:

$wgPasswordDefault	Algorithm	Class	Strength	Notes
A	MD5	MWOldPassword	Insecure by modern standards
B	MD5	MWSaltedPassword	Insecure by modern standards	It involves running MD5 on the password, and then running MD5 on the salt concatenated with the first hash.
pbkdf2-legacyA	PBKDF2	LayeredParameterizedPassword
pbkdf2-legacyB	PBKDF2	LayeredParameterizedPassword
bcrypt	Bcrypt	BcryptPassword	Moderately secure
pbkdf2	PBKDF2	Pbkdf2PasswordUsingOpenSSL	Moderately secure	Default for new MediaWiki installations as of 2026.
argon2	Argon2	Argon2Password	Most secure of currently supported options	Used by Wikimedia websites as of 2026.

After changing this setting, users will have their password updated to the new format on next login.

Changing the default

1. Check the "DefaultSettings.php" file in the ../includes directory for the available and preset password encryption types.
   (As of MW 1.33: A, B, pbkdf2-legacyA, pbkdf2-legacyB, bcrypt, pbkdf2, argon2)
2. Add $wgPasswordDefault with the parameter to the "LocalSettings.php" file in case you want to change the encryption, e.g. to restore the old MD5 hashing:

   $wgPasswordDefault = 'B';
   

3. In order for the password to be saved in a new format, one login from each user has to be done. This way the database is updated.
   Alternatively you can use the wrapOldPasswords.php maintenance script to convert the hashing algorithm of all passwords without waiting for users to log in. Note that this script only works for pbkdf2-legacyA, pbkdf2-legacyB.
4. Check in the MySQL-database whether the new format has been applied to the fields.

   Select user_password from wikidbname.user where user_password like ':B:%';
