When you're insering a new password:
INSERT INTO user SET password=PASSWORD('secret');
But you can't retrieve the original password. If a user forgets/looses
his/her password, just reset a password with something else, and send
him/her that new password
And when you want to check an inputted password agains the encrypted one;
SELECT * FROM user WHERE login="user_id" AND
password=PASSWORD("inserted_password");
