I can't sign in to my account

Password not working, Google sign-in not finishing, or account blocked? Every message and how to fix it.

Last updated: October 23, 2026 3 min read

No problem, this is one of the problems with the quickest fixes. Look for the message you're seeing.

The 30-second fix

  1. Check your email: no extra space, no missing letter, and no missing ".com".
  2. Tap the eye icon next to the password, so you can see what you've typed.
  3. Signed up with Google the first time? Sign in with the "Continue with Google" button, not with your email and password.

If you see "The email or password is incorrect."

  • If you don't remember your password, make a new one from Forgot your password, or want to change it.
  • If you used to sign in with Google, your account might not have a password you know. Sign in with "Continue with Google".
  • Try your other email, if you have more than one.
The Teacher sign in page with the message The email or password is incorrect.
This message means something's wrong with the email or the password

If you see "Too many sign-in attempts for this account"

A wrong password was typed several times, so signing in with a password has been paused for a while to protect your account. You have 3 options:

  • Wait about an hour and try again.
  • Or sign in with "Continue with Google" if your email is a Gmail address.
  • Or change your password from "Forgot your password?".

If Google sign-in doesn't finish

Message What to do
"Google sign-in didn't finish. Try again." or "The Google sign-in didn't finish." Try again, and go all the way through choosing your account without closing the window.
"We couldn't verify the Google account. Please try again." Try again in a moment, and make sure your device's time and date are right.
"The Google sign-in timed out. Please start again." The Google page was opened too long ago. Press "Continue with Google" again from the start.
"We couldn't open the browser. Open it and try again." (Windows) Open any browser, then come back and press "Continue with Google".
"Unexpected reply from the browser. Start Google sign-in again." (Windows) Close the Google page, and press "Continue with Google" again.
"The Google sign-in has expired. Start again from the 'Sign in with Google' button." You took a little too long choosing. Start from the beginning.
"Signing in with Google isn't available right now. Sign in with your email and password." Sign in with your email and password, or make a password from "Forgot your password?".

If you see "This email is already registered. Sign in to your account."

This shows up when you're creating a new account: it means you already have an account with this email. Press "Sign in" and sign in with it, or make a new password if you don't remember yours.

If you see "This account can't sign in"

If you see "This account can't sign in from the app." or "This account can't sign in with Google.", this account has been suspended or deleted, or it isn't a teacher account. Email us at [email protected] from the same email.

If you were signed in and suddenly got signed out

  • In the app, "You've been signed out on this device. Sign in again to continue.": your password was changed, someone pressed "Sign out of all devices", or your email was changed. Sign in again. If it wasn't you, change your password.
  • On the lesson page in the browser, "Sign in again": your session on the website has ended. Press "Sign in", and you'll come back to the same page.
