From the top menu bar, select User accounts (2). Under Action, click Edit Privileges (3) for user fred. The Edit Privileges: User account 'fred'@'127.0.0.1' page is displayed.

## Edit Restricted MySQL User using MySQL Console Editing an existing user with restricted privileges can be performed using the MySQL Console. You can use REVOKE to remove some or all privileges, or alternatively use GRANT to add additional privileges. This example assumes a user fred has been created with the privileges GRANT SELECT, INSERT, UPDATE, DELETE assigned on database wordpress. You can revoke (remove) privileges; for example, the following command removes INSERT, UPDATE and DELETE. `REVOKE INSERT, UPDATE, DELETE ON wordpress.* FROM 'fred'@'127.0.0.1' ;` You can grant (add) privileges; for example, the following command adds INSERT and UPDATE. `GRANT INSERT, UPDATE ON wordpress.* TO 'fred'@'127.0.0.1' ;` You can display the grants assigned with the following command: `SHOW GRANTS FOR 'fred'@'127.0.0.1';` Example for the above commands Open MySQL Console window by clicking on MySQL Console button. Then enter the following commands: `SHOW GRANTS FOR 'fred'@'127.0.0.1';` `REVOKE INSERT, UPDATE, DELETE ON wordpress.* FROM 'fred'@'127.0.0.1' ;` `SHOW GRANTS FOR 'fred'@'127.0.0.1';` `GRANT INSERT, UPDATE ON wordpress.* TO 'fred'@'127.0.0.1' ;` `SHOW GRANTS FOR 'fred'@'127.0.0.1';` `exit` The results are shown below:
