As far as I know I’ve never tried to create an Auth0 account through my GitHub user but when I tried it (after approving the OAuth in github.com) Auth0 asks me for an MFA token — which, again, I’ve never set up to the best of my knowledge. Is there some way to reset the account? Whatever’s in there is obviously not essential. I’m a little frustrated there isn’t any formal account recovery support page/contact so I hope this is the right place to post this.
Welcome to the Auth0 Community!
Sorry for the frustrating experience. It sounds like you may simply need an MFA reset. Can you please follow the instructions in this FAQ: Account Locked: MFA Resets Requests.
