I want to change the email associated with my account
You can assign the email associated with your Screencastify account to another email address.
IMPORTANT: If you switch the email address associated with your account, you will no longer be able to access your existing recorings that are saved in the previous Google account. However, if you original email account was connected to Google Drive, your recordings will still be saved there.
