Don’t remember your username? No problem. Both your Teacher and your connected Parent can tell you your Username (and reset your password if necessary!)
Simply ask your teacher to look up your Username in the "Members" tab of your group, where your teacher can also reset your password.
If you connected your account to your Parent's Edmodo account, they can find your Username (and reset your password) too. To do this, your Parent will go to their "Students" tab in their account settings where they'll see your Username underneath your name.
If you have an email address associated with your account, you can use your full email address as your username. This means you can either login with your username or your full email address.
If you are having trouble logging in, please see the forgot your password page for help getting logged in.
Also, please note that usernames cannot be changed. Usernames will never be visible to anybody except your teacher, but if you would like a new username, then you will have to sign up for a new account.
