You can also log in with your AMBS or EMS G Suite account. (EMS students: you must do this to create your Moodle account for your class at AMBS.)
Note: if you have changed your email address in Moodle, or if you do not have an AMBS or EMS email address, then you won't be able to sign in with your G Suite account. Log in using your Moodle username/password, or use the password reset link to reset it.
