: This article describes how to change the password of a mysql User. if you are interested in the PHP Tutorial, refer to it. 1: Use the set password command
First, log on to MySQL.

Mysql> use mysql;
Mysql> update user set password = password ('000000') where user = 'root' and host = 'localhost ';

Take windows as an example:
1. disable the running MySQL service.
2. open the DOS window and go to the mysql \ bin directory.
3. enter mysqld -- skip-grant-tables and press enter. -- Skip-grant-tables indicates that the permission table authentication is skipped when the MySQL service is started.
4. open another DOS window (because the DOS window can no longer be moved) and go to the mysql \ bin directory.
5. enter mysql and press Enter. If yes, the MySQL prompt> will appear.
6. connect to the permission database: use mysql ;.
6. change the password: update user set password = password ("123") where user = "root"; (do not forget the last Plus points ).
7. refresh permission (required): flush privileges ;.
8. exit quit.
9. log out of the system and log on again. log on with the username root and the new password 123 you just set.
