Looks like you've scanned our example of a QR code pictured in our help article. This code is simply an example of what you're code will look like when you generate it in OnPay.
To setup MFA using your unique QR code, log into OnPay, then go to My Profile, and click Enable MFA.
Keep in mind that, when setting up multi-factor authentication, or any login-security measure, a common method is to generate a one-time use code that is unique to you and your account. Setting up a secure account will always require a step where a unique authentication code is generated just for you.
Never use a code that's shared, or that's available to the public.
