  • Open FAQ in new window Gmail: Oauth2 support
  • As of October 3, 2022, the Oauth2 method used by POP Peeper v4 has been phased out by Gmail. POP Peeper v5+ supports the Oauth2 method that Gmail requires; however, it may not fully work with older versions of Windows (e.g. Windows 7).

    Windows 10/11 and newer - It is recommended that you update to the latest version of POP Peeper and use Oauth2; you should not encounter any problems with this configuration.

    Windows 7 and older - You have 2 choices:

    • Use Oauth2: Exit POP Peeper and then run POP Peeper with elevated/admin privileges (right-click on the POP Peeper shortcut and select 'Run as administrator'; to access a POP Peeper shortcut, you can open the Windows start menu and type 'POP Peeper') and then authorize your Gmail account(s) with Oauth2. Make sure that you use the "web browser" method. Note that POP Peeper only needs to run with admin privileges when you need to authenticate Oauth2 with your webbrowser; that is, you SHOULD NOT run POP Peeper as admin to access your email once you've authenticated Oauth2. Gmail may require you to authenticate Oauth2 again in the future, which will require you to run POP Peeper with admin again (however, in most cases, this does not occur very often).
    • Use an App password: An app password is simply a different password from your main password that can only be used to access your email. Gmail requires that you enable 2-step verification on your account to use this method. For more information, click the following link: https://support.google.com/accounts/answer/185833?hl=en
