Locked out of Auth0 Dashboard (sole admin) only prompts for “Security Key” (WebAuthn), no recovery

Hi, I’m locked out of my Auth0 Dashboard tenant and can’t access admin settings.

  • Tenant domain: sapiensv2.au.auth0.com
  • Plan: Free
  • Sole admin email: rolandd@sapiensv2.com
  • Issue: Login suddenly changed to only prompt for Security Key (WebAuthn). It no longer offers Windows Hello PIN/biometrics or email code.
  • I do not have any MFA recovery codes and do not have a security key enrolled/available.
  • I’ve tried multiple browsers and private/incognito sessions.

Can someone advise the correct process for Dashboard admin MFA reset / account recovery for this tenant when there is only one admin?
