If the code from your 2FA app isn't working when you log in to Airtm, follow these steps in order:
Step 1 — Sync your app's time The most common cause is a time mismatch. In Google Authenticator, go to Settings > Time correction for codes > Sync now. In Authy, time syncs automatically — try restarting the app if the code still fails.
Step 2 — Make sure you're using the right code If you have multiple accounts in your 2FA app, confirm you're using the code for Airtm specifically, not another platform.
Step 3 — Wait for a fresh code Each code is valid for 30 seconds. If your code has less than 5 seconds remaining when you enter it, wait for the next one before trying again.
Step 4 — Reinstall the 2FA app If the steps above don't work, uninstall and reinstall Google Authenticator or Authy, then re-link your Airtm account by scanning the QR code in Settings > Security.
Lost access to your phone or the app?
If you no longer have access to the device where your 2FA app was installed, you won't be able to generate a code on your own. In that case:
- Go to the Airtm login screen.
- Select "Having trouble with your 2FA code?" (or the equivalent recovery link).
- Follow the account recovery process.
If you can't find that option or the process doesn't work, submit a support ticket through the email support@airtm.io stating that you've lost access to your 2FA. Our team will walk you through recovering your account securely.
