Two-factor authentication (2FA) provides an extra layer of security for your account. It requires both a password and a single-use digital key when logging into your account. Two-factor authentication increases protection for your accounts and prevents them from unauthorized access.

If you’re having issues with your authenticator application, check the following troubleshooting steps.

​
Check apps’ time synchronization

Two-factor authentication (2FA) requires synchronized time with the login device to ensure the confirmation method stays up to date. If you get an invalid code message but are sure the code is correct, it might be the app’s time synchronization issue.To resolve this issue, make sure that the date and time are set correctly, and enable network time synchronization on the device you’re using to log in.

​
Use a backup verification code

Use one of the one-time backup codes that were generated during the setup of 2FA.

​
Check your device configuration

If you recently changed the device with your authenticator app, check the application settings to verify that it’s configured correctly on the device.
4. Scan the QR code from the pop-up window in your authenticator application. 5. Enter the six-digit code generated by the app and click Check.
