  • Open FAQ in new window What is OAuth2 (AKA modern authentication)?
  • OAuth2 is a secure method for logging into IMAP and SMTP accounts. Instead of POP Peeper sending your password to login, POP Peeper sends a unique key which changes frequently. This method is more secure than the traditional login method, and is recommended when available.

    POP Peeper supports OAuth2 login for Gmail, Yahoo/AOL and Outlook/Hotmail.

    In order to enable and use OAuth2 for each account, you will need to edit your account in POP Peeper, press the 'OAuth2' button and then follow the instructions to allow POP Peeper to access email in your account. When using OAuth2, it is recommended that you delete the login password, as POP Peeper will not need it to login.

    To disable OAuth2 support in POP Peeper, edit the account and change the "Oauth2" selection to "password" (next to your login name on the 'General' page). To delete the existing Oauth2 credentials, you can select Oauth2, confirm the prompt to delete the credentials, and then cancel the subsequent request for Oauth2 (it is not necessary to select "password" first).
