From the MobLab Instructor Console
You can reset your password by going to the Account dropdown and selecting the My Account option.
From there, choose the Password tab next to your Profile tab. Enter your new password, being mindful of the password requirements below. Finally, re-enter your new password in the Confirm Password textbox and don't forget to press Save!
If you are unable to first log into the MobLab instructor console (perhaps because you forgot your password), you can also reset your password by going to https://game.moblab.com and selecting the Forgot Password? link.
