Authentication codes can occasionally fail due to small timing differences between your device and the server. This is a common issue

To resolve this, try ensuring your device’s date and time are set to update automatically. Then generate a new code and try again. If needed, restarting the setup process can also help.

Common causes

Step 1: Sign in

• Go to the login page and sign in with your username and password
• When prompted, complete the Secure My Account step

Step 2: Enter your code

• Open your authenticator app
• Enter the latest 6-digit code

Step 3: If the code isn’t accepted

Sync your device time

• Turn on Set date and time automatically

Try a new code

• Open your authenticator app

Restart setup (if needed)
