See Authentication from MariaDB 10.4 for an overview of authentication changes in MariaDB 10.4. If you attempt to run SET PASSWORD on an account that authenticates with one of these authentication plugins that doesn't store a password in the mysql.global_priv table, then MariaDB Server will raise a warning like the following: SET PASSWORD is ignored for users authenticating via unix_socket plugin These authentication plugins rely on other methods to authenticate the user. The unix_socket, named_pipe, gssapi, and pam authentication plugins do not store passwords in the mysql.global_priv table. Because, the MySQL root user is set to authenticate using the authsocket plugin by default instead of the password in Ubuntu systems running MySQL 5.7 and newer versions. The authentication plugin hashes the password with a method that is compatible with that specific authentication plugin. Introduction Even if you have setup password for MySQL root user, you still can't authenticate with the database server as root user with a password. from 'user''host' Then grant the appropriate privileges as desired: grant SELECT,INSERT,UPDATE,DELETE ON db. If you run SET PASSWORD on an account that authenticates with one of these authentication plugins that stores passwords in the mysql.global_priv table, then the PASSWORD() function is evaluated by the specific authentication plugin used by the account. 117 To list users: select user,host from er To show privileges: show grants for 'user''host' To change privileges, first revoke. The ed25519, mysql_native_password, and mysql_old_password authentication plugins store passwords in the mysql.global_priv table. In MariaDB 10.4 and later, SET PASSWORD (with or without PASSWORD()) works for accounts authenticated via any authentication plugin that supports passwords stored in the mysql.global_priv table. The argument to PASSWORD() and the password given to MariaDB clients can be of arbitrary length. er table (or view in MariaDB-10.4 onwards) entry. Given in format, where user_name and host_name areĮxactly as they are listed in the User and Host columns of the Privilege for the mysql database can do this. With a FOR clause, this statement sets the password for a specificĪccount on the current server host. Any client that has connected to the server using a non-anonymousĪccount can change the password for that account. With no FOR clause, this statement sets the password for the current OLD_PASSWORD() should only be used if your MariaDB/MySQL clients are very old (< 4.0.0). Should be the already-encrypted password value as returned by Password is specified without using either function, the password If the password is specified using the PASSWORD() or OLD_PASSWORD()įunction, the literal text of the password should be given. ![]() So your UPDATE command to directly change the password on the grant tables have to look like this, using the correct column and the FLUSH PRIVILEGES statement: UPDATE mysql.The SET PASSWORD statement assigns a password to an existing MariaDB user Source: When Privilege Changes Take Effect This can be done by issuing a FLUSH PRIVILEGES statement. To tell the server to reload the grant tables, perform a flush-privileges operation. This may leave you wondering why your changes seem to make no difference! Thus, if you change the grant tables directly but forget to reload them, the changes have no effect until you restart the server. ![]() If you modify the grant tables directly using statements such as INSERT, UPDATE, or DELETE ( which is not recommended), the changes have no effect on privilege checking until you either tell the server to reload the tables or restart it. In case you directly change the grant tables you also have to reload the tables by using the FLUSH PRIVILEGES statement: The password column, previously used to store password hash values for accounts authenticated with the mysql_native_password and mysql_old_password plugins, is removed. The authentication_string column in the er table now stores credential information for all accounts. Your UPDATE command perhaps doesn't work because the password column get replaced by authentication_string on MySQL 5.7.6. More information on MySQL: Assigning Account Passwords ![]() You should use SET PASSWORD instead: SET PASSWORD FOR = PASSWORD('elephant7') It's not recommended to change the password in this way using UPDATE directly on the er table.
