K-9: gmail authentification failing

[etourmi]

Hello,

Help!

From all my Android phones and with all my accounts I can't no longer send mails using my gmail accounts in k9 mail (auth plain failed).
I still can connect to my gmail accounts on my Android phones by using the gmail app or any web browser.

Has Google changed something today with k9mail ?

Regards,

(Command: sensitive; response: #3#[NO, [AUTHENIFICATIONFAILED], invalid credentials (Failure)])
I changed nothing for the past many months

Happens on my phone as well (android 7). Cannot fetch from or add a new Gmail account.

Happened on the 5.600 from Google Play, switched to the 5.709 from F-Droid, issue persists.

Noticed the issue first at 12 Paris time.

"Same here" will lead to around 350 people being notified without adding value. Please don't do that.

But my accounts work in Thunderbird, why not K-9 Mail ?

Google also recently broke OAuth2 with Thunderbird 60.x.x ... forced to upgrade to Thunderbird 68.x.x to handle the new workflow.

Google also recently introduced resetting your 'Allow untrusted mail clients' (or whatever that setting is) if you do not access it via some non Google client for a log time.. Just overwrites your deliberate personal setting. An awful customer interface choice.

ok it works with the 2 step verification.
The new password has to be generated by Google itself.

My 2-Step Verification enabled account with app password has not affected,
but 'Use your phone to sign in' enabled account had this issue.

I turned off and on "Less secure app access" and finally it's working!

It was on but it seems that Google reset some internal information.

I'm using Gmail with K-9 without issues. Enabled 2FA via authenticator app (TOTP) and generated application-specific password for K-9 and my other mail client. (Gmail has had you generate a app-specific password for each of your apps for since I remember, at least 5-10 years)

[Littlemac123]

is there a way to fix this with out setting up 2 step Verification

[rihoward]

It might be that the gmail service is treating K9 Mail as a "less secure app" depending on your gmail settings.
See:
https://support.google.com/accounts/answer/6010255
If this is the source of the problem then K9 Mail should team should see how it can comply with that.
