To set up the authenticator app for your WordPress login:
- On your phone, install Google Authenticator or Authy from the App Store or Play Store.
- Log in at your site’s login address. The site shows a QR code.
- In the app, add an account and scan that QR code.
- Enter the current 6-digit code the app shows to finish.
After setup, every future login asks for the current code from the app.
