mysql password life time to set and reset for global or for user

At script level you will get this message. Your PhpMyAdmin will also give you error message.

Error: Unable to connect to MySQL.

Debugging errno: 1862
Debugging error: Your password has expired. To log in you must change it using a client that supports expired passwords.

Open your MySQL Command Line Control
Enter your password ( it will accept ) and then enter this

SET GLOBAL default_password_lifetime = 0;

The password will never expire now.

To update password

ALTER USER 'usrname'@'localhost' IDENTIFIED BY 'new-password';

To expire any user account

ALTER USER 'user_id'@'localhost' PASSWORD EXPIRE;

Not to expire any user password

ALTER USER 'my_userid'@'localhost' PASSWORD EXPIRE NEVER

To set the password duration for all the users ( global ) , 60 days

SET GLOBAL default_password_lifetime = 60;

For a user to set a different days than the global set value

ALTER USER 'userid'@'localhost' PASSWORD EXPIRE INTERVAL 30 DAY;

In all these cases MySQL keeps the user in Sandbox Mode , that is the user is allowed for changing the password only.
