Expiring User's Password
This tip was authored by Jim Knicely.
You can expire a user’s password immediately using the ALTER USER statement’s PASSWORD EXPIRE parameter.
By expiring a password, you can:
• Force users to comply with a change to password policy.
• Set a new password when a user forgets the old password.
This feature also comes in handy when you as an admin are asked to replicate users on one database to another. You can easily create the remote user, but how do you set the user’s password being that you don’t know the password? That’s where the PASSWORD EXPIRE parameter comes to the rescue. Simply create the user then expire the user’s password. This will require the user to set their password the next time they log on.
