Sign in

I can't sign in to Classroom

You may be trying to sign in to Classroom with the wrong account. Check that you’re using the email account connected to Classroom. You sign in to Classroom with one of these accounts:
  • A G Suite for Education account (you@yourschool.edu) that your school creates. If you don't know your G Suite for Education account, ask your teacher. 
  • A personal Google Account (you@example.com) that you create. Learn more about how to create a Google Account.
Note: You must have an active Internet connection to sign in.
If you can’t sign in with the correct email account and password, maybe your school’s administrator doesn’t automatically activate Classroom for new students and users. Ask your teacher.

I forgot my password

If your school uses G Suite for Education—Ask your teacher to contact the admin to reset your password.
If you’re a student using a personal Google Account outside of a school—See Change or reset your password.

How do I switch between user accounts?

If you need to sign in with a different user account, see Switch between accounts.

Sign out

How do I sign out?

Note: On Android, you can’t sign out of an account - you have to remove your account. You can easily add your account again. Removing the account from your phone or tablet won't delete the account itself, so you'll still be able to use it on a computer or other devices. Learn more about accounts.

Classes

My class code doesn't work

If your school uses G Suite for Education—Ask your teacher to send you a new class code. If the new class code doesn’t work, ask your teacher to contact the school’s admin.

If you’re a student using a personal Google Account outside of a school—Ask your teacher to send you a new class code.

A class code consists of 6 or 7 alphanumeric characters. For example, hjhmgrk or g5gdp1.

Note: You only use the class code once to enroll. You don't need to re-use the class code. 

I deleted or forgot my class code

If you deleted, lost, or forgot the class code before adding yourself to a class, ask your teacher to resend the code or set a new one.

Note: You only use the class code once to join the class. You are then enrolled in the class and you don't need to re-use the code again.

I deleted my class invitation

If you lose your class invitation before you added yourself to a class, ask your teacher to resend the class invitation.
Note: You only use the class invitation once to enroll. You don't need to re-use the class invitation again.

I unenrolled from a class and want to re-enroll

If you accidentally unenrolled from a class, ask your teacher to resend you a class code or invitation.

How do I create a class?

If your school uses G Suite for Education—Students can’t create classes.
If you’re a student outside of a school using a personal Google Account—See Create a class.
