Hey there! 👋

Thanks for posting in the GitHub Community, @0xtunex ! We're happy you're here. You are more likely to get a useful response if you are posting in the applicable category and including as many relevant details as possible. The Accessibility category is a place for our community to discuss and provide feedback on the digital accessibility of GitHub products. Digital accessibility means that GitHub tools, and technologies, are designed and developed so that people with disabilities can use them.

I've gone ahead and moved this to the correct category for you, General. Good luck!

This issue usually happens when GitHub’s OAuth verification fails during the login handshake with Vercel or Netlify. A few things you can try that often resolve it:

1. Check your GitHub account permissions

   • Go to GitHub → Settings → Applications → Authorized OAuth Apps.
   • Find Vercel or Netlify and remove them.
   • Then try signing in again — you’ll be prompted to re-authorize GitHub.

2. Clear browser cache & cookies / try incognito mode

   • Cached sessions or expired tokens often cause the “verification failed” error.
   • An incognito/private window ensures a fresh OAuth flow.

3. Verify primary email on GitHub

   • Go to GitHub → Settings → Emails and check that your primary email is verified.
   • Some providers reject unverified accounts.

4. Check 2FA (Two-Factor Authentication)

   • If you recently enabled 2FA on GitHub, make sure it’s fully set up.
   • Try signing out everywhere and back in.

5. Try another browser or disable extensions

   • Extensions (especially ad-blockers, privacy add-ons) can block OAuth pop-ups or cookies.

6. As a last resort: revoke & re-connect

   • Go to GitHub → Settings → Applications → Authorized OAuth Apps → Revoke Access.
   • Then go back to Vercel/Netlify and log in again with GitHub.

✅ If none of the above fixes work, it might be a temporary issue on Vercel/Netlify’s end. In that case, check their [status pages](https://www.vercel-status.com/) or [Netlify status](https://www.netlifystatus.com/).

👉 Usually, re-authorizing the app in GitHub + clearing cache fixes this for most people.

It looks like you're encountering a common issue when trying to authenticate with GitHub on either Netlify or Vercel. Let's break this down and troubleshoot each service step by step.

Netlify — “Verification Failed” or Authentication Errors

Common Scenario & Fix:

• Issue: You get errors like:

  • “We already have a registered user with this email address.”

  • “Your account requires additional verification.”

• Why It Happens: GitHub-authenticated accounts and email/password accounts can conflict if they share the same email.

• Solution:

  1. Log in with email and password (not GitHub).

     • If you don’t have a password yet, use the password reset form to set one up.

  2. Once logged in, go to Settings → Connected Accounts and disconnect or update the GitHub account linked to your Netlify account.

  3. Log out, then try signing in again—this time using GitHub.

     • At this point, both login methods should work.

If You See “Account Requires Additional Verification”:

• This usually means Netlify flagged your account for extra checks:

  • You might not receive the verification email, even in your spam folder.

• Best Next Step: Submit a support request through their helpdesk, specifically choosing “Login/Signup” as the issue category.
