No Sync to Garmin after activating ECG and 2FA

[colonel302]

I have a problem to sync since 25.12. with Version 4.2.7. I get this error:

Hello, if you are sure the username/password combination is still correct, try upgrading garth.

[colonel302]

Hi,
username/password works at the Garmin Connect.
Garth is @ 0.4.46 which is needed for withingssync 4.2.7. The Update to garth 0.5.2 shows the same error.

[colonel302]

Good morning,
I think it is a problem with the permanent MFA which was enabled using ECG from Garmin.
Changeing to credentials via environment variables does not help.

[stynoo]

Ah Garmin doing Garming things again...
So to get what happened correctly... This didn't suddenly stopped working, you added a new device with ECG functionality and Garmin is required by law to enable MFA/2FA when processing ECG data.
Garth should work with this, I am not sure why it goes wrong.

[colonel302]

It seems so. Any ideas on how to get it working again? I have also deactivated the ECG function again. Unfortunately, I can no longer deactivate the 2FA in the profile. I have written to Garmin support about this.

[michaelknox]

I am seeing the same on my side. Again with the ECG function and most likely the 2FA. I'll send them a note as well.

I had the same problem after activating ECG. I removed the .garmin_session in my homedirectory to re-authenticate to Garmin.
This will request a new securitycode.
For me it is working again after this.

Thank you so much. This worked for me. After deleting I Was asked for mfa Code and the sync works.
