To disassociate your Google Account: Click the square grid icon on the Google homepage > My Account > Sign in & Security > Apps with account access > Manage Apps > PBS App > Remove Access > Confirm
If you no longer have access to your Google account, or the above doesn’t work, please try the following:
Go to https://account.pbs.org/oauth2/send-reset-password, enter email address, and click the green reset button. You’ll get an email with subject “Reset Your PBS Password” with a link inside to create new password.
Clicking the link will take you to the screen below. Enter new password twice then hit “Reset”.
This will set a password for your PBS Account, which is not associated with Google. This means that on all PBS websites you can choose the “Sign in with Email” option and login with the same email address and the password you just created. After this process, you should no longer be prompted to sign in with Google.
