Altering database users
You can use the ALTER USER command to change the name, password, expiration, owner, and session settings of an existing database user account.
You can also unlock an account if it was configured to lock after a specified number of failed

SYSTEM.ADMIN(ADMIN)=> ALTER USER dlee WITH IN RESOURCEGROUP silver;
