Mysql forgotten password operation

I forgot my mysql password. After searching online for a long time, I finally found something that works.

1. Terminate the MySql service

Right-click-Manage-Service-MySql-Stop service

or

Open cmd as administrator and execute:

net stop mysql

2. Skip password entry for authorization

 mysqld --console --skip-grant-tables --shared-memory 

3. Re-open a cmd window (don’t close the previous cmd window), reset the password, and execute:

mysql -uroot -p

At this time, the password has been bypassed to log in to mysql.​ 

Change the password and set it to blank

UPDATE mysql.user SET authentication_string='' WHERE user='root';

4. Close all command line interfaces, open the MySql service normally and then log in (when a data password is required, just press Enter)

use mysql 

#Set the password to 123456

ALTER user root@'localhost' identified by '123456';

or can

Set encryption rules and update new password and authorization (directly copy these SQL statements and your password will be updated to 123456)

ALTER USER 'root'@'localhost' IDENTIFIED BY '123456' PASSWORD EXPIRE NEVER; 
alter user 'root'@'localhost' identified by '123456';
grant all privileges  on *.*  to "root"@'localhost';
flush privileges;

5. The password is set successfully, restart mysql and log in with the new password.

net start mysql
