MySQL5.7 change password

I haven't used Mysql very often. Today, I have a small program that I need to use, but I forgot how to change the user password. Search the Internet and record it.

1 update user set authentication_string = password('root'), password_expired = 'N', password_last_changed = now() where user = 'root';

It takes effect after restarting the MySQL service.
