Incorrect time settings on your mobile device are a common cause of invalid two-step verification security codes.

To fix this, you must synchronize time settings on your device:

• On your device, choose automatic date and time.
• If this does not resolve the problem, you may want to receive your two-step verification codes via email.

Google Authenticator for Android users can also try the following:

1. Run the app
2. Tap the ... menu dots and choose Settings
3. Tap Time correction for codes.
4. Tap Sync now.
