Disable permanent 2FA

I have enabled ECG app and I had to enable two factor authenticaton. 

Now third party apps such as Biometric Explorer have stopped working.

Is there a way to disable ECG app and disable MFA in order that apps work again? I do not care about deleting ECG data

  • Once enabled, the 2FA functionality can’t be disabled. I made the same mistake, curious about ECG use, but after finding it wasn’t helpful, I deleted the app and tried to revert to the normal login process. Garmin support told me it’s irreversible. They offered me two options:

    1. Live with it.
    2. Download my data, delete my account, create a new one, and restore the data.

    I decided the risk of losing data wasn’t worth it. While I find this limitation absurd, I’ve learned to live with it despite the bugs and inconveniences.
