Introduction

You’re ready to push your latest code to GitHub, but GitHub 2 factor authentication not working leaves you stuck—no authenticator code, no repository access, just frustration. GitHub’s two-factor authentication (2FA), often managed via apps like Google Authenticator or Microsoft Authenticator, adds vital security, but glitches can halt your workflow. Don’t let 2FA issues derail your coding projects in 2025! This guide offers rapid solutions to get you back to collaborating, and if you’re after a smoother experience, Authenticator App ® 2FA delivers iCloud sync and biometric login for effortless GitHub access.

Why Is GitHub 2 Factor Authentication Not Working?

Several factors can cause GitHub 2 factor authentication not working:

• Time Sync Errors: A mismatched device clock can invalidate TOTP codes.
• Lost Authenticator Data: Switching devices without transferring app data blocks 2FA.
• Expired or Invalid Codes: Codes expire every 30 seconds, and errors in entry fail authentication.
• Missing Recovery Codes: Losing backup codes leaves you without a fallback.
• Network Issues: An unstable connection can disrupt code generation or verification.
• Outdated Software: An outdated authenticator app or GitHub client can cause compatibility problems.
• Browser Conflicts: Cached data or extensions (e.g., ad blockers) may interfere with 2FA prompts.

Understanding these causes is the key to fixing GitHub 2 factor authentication not working.

How to Fix GitHub 2 Factor Authentication Not Working

Here are practical steps to resolve GitHub 2 factor authentication not working and regain access to your repositories:

1. Verify Your 2FA Code and App
