Supabase Auth errorSupabase Auth: mfa_verification_failed

Rather not fix it yourself? App Fix Ticket starts with a fixed-price diagnosis, then a fixed price for the fix before any fix work.

Why the code is rejected, and the fix

1. 01

   The code was typed wrong or too late

   “If not, you should repeat steps 2 and 3.” Supabase docs, Multi-Factor Authentication (TOTP)

   Authenticator codes change every few seconds. Show a short message, clear the field, and run challenge and verify again with the new code.

   const { data: challenge } = await supabase.auth.mfa.challenge({ factorId });
   const { error } = await supabase.auth.mfa.verify({
     factorId,
     challengeId: challenge.id,
     code,
   });
   if (error?.code === 'mfa_verification_failed') {
     showMessage('That code didn’t work. Enter the newest code from the app.');
   }

2. 02

   enroll ran twice during setup

   A screen that calls mfa.enroll on every render can show one QR code and keep the factorId of another. Call enroll once and keep its QR code and ID together.

3. 03

   The phone clock is off

   TOTP codes depend on the time. A phone with a manually set clock produces codes the server won’t accept. Ask the user to turn on automatic date and time.

4. 04

   The user has several factors

   Also check: after a few abandoned setups, a user can have more than one TOTP factor. Use listFactors, verify against the one marked verified, and unenroll the rest.

Checked against the vendor’s docs on November 9, 2026: Supabase docs: Auth error codes; Supabase docs: Multi-Factor Authentication (TOTP).
