There are two ways to enable two-factor authorisation:
1. Scan the QR Code above with a two-factor app on your phone.
e.g.: Authy, Google Authenticator or FreeOTP.
The app can be then used to create your 6 digit code to enter into the box above.
2. Alternatively, you can use the 16 digit code code displayed above to manually add to either of the apps above, a password manager or digital vault which can then be used to create your 6 digit code to enter into the box above.
