Receiving emails - IMAP Authentication with OAuth 2.0

Added by Sir Will about 3 years ago

Hello,

is there currently any option to configure the receiving of emails with IMAP via OAuth? I'm currently using Gmail with plain Username + Password authentication, but this will probably no longer work soon:

Starting May 30, 2022, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password.

Anyone with a solution to this?

I think the procedure described on this page may be helpful. I have not tried it yet.

I have created an App Password now, which requires 2FA to be enabled for the Google account, but seems to work so far. (https://support.google.com/mail/answer/185833)

Hello, I'm trying to change the email fetcher script (lib/tasks/email_oauth.rake) to get mails from google (gmail) but without success.
Has anybody been able to fetch email via imap authenticated with oauth from gmail?

Last time, google postponed this closure, but a new date also passed (2025-03-14). Password authentication still works for IMAP, but who knows till what time.

Finally I have succeeded. I can fetch emails with oauth. I will clean up my solution, and share it somewhere.
Thank you for the links and inspiration.
