Fixing 2FA Problems

Two‑factor authentication (2FA) adds an extra layer of security to your account, but issues can occur if your device time is incorrect, your authenticator app isn’t synced, or backup codes are missing. This guide explains the most common causes of 2FA failures and how to resolve them.

⏱️ Check Your Device Time and Date

Incorrect device time is the #1 cause of invalid 2FA codes.

Authenticator apps rely on accurate time to generate valid codes.

🔄 Sync Your Authenticator App

Some authenticator apps allow manual time sync.

If the app is out of sync, codes will be rejected.

📱 Try a Backup Code

If your authenticator app isn’t working:

If you lost your backup codes, continue to the next steps.

📲 Check for App or Device Issues

Your authenticator app may not be generating codes correctly.

If the app is malfunctioning, codes may be invalid.

🛡️ Disable VPNs or Proxies

VPNs can cause login or verification issues.

If login works without the VPN, the issue is network‑related.

🌐 Try Another Browser or Device

Browser issues can block the 2FA prompt or code submission.

If 2FA works elsewhere, the issue is browser‑specific.

🔐 Check for Account Lockouts

Too many incorrect 2FA attempts may temporarily lock your account.

Lockouts protect your account from unauthorized access.

🧩 Reset 2FA (If You Still Have Access)

If you can log in using a backup code:

This resolves most long‑term 2FA issues.

📬 Contact Support if You’re Locked Out

If you cannot access your account at all, the support team can help verify your identity and restore access.

Include your account email and describe what happens when you enter your 2FA code.
