Once you have done this, click on your name in the top right corner of your screen from any page when logged into your Staff Squared account and select 'enable two-factor authentication'.
A QR code and a keycode will appear on the next page. You can use these to either scan or enter into your authenticator app which will generate a six-digit verification code. Click continue and enter this code onto the next page and click continue again.
NB: Be sure to enter the code before it expires!
On the next page, click enable two-factor authentication. This will generate a recovery code - make a note of this code as you will need it if you lose or replace your phone, or lose access to your authenticator app.
Once finished, click complete.
