After you have attended an ART day course (M1, M2F or M2C) you will be registered on both SmART Ringer and ART Online. Your username and password will be the same on both systems.
If you change your SmART Ringer password, your ART Online password will automatically be updated. You cannot change your password from within ART Online.
However, if you already had an account for ART Online before your SmART Ringer account was created, the passwords are entirely independent. You can change either of them without affecting the other.
