When you take a selfie, we don’t then use the photo itself, so there’s no need to change or update it. We create a biometric face template from your photo, basically a string of numbers based on a few key features of your face, such as the distance between your eyes or the shape of your jaw or nose.
When you log in or verify yourself, the system doesn’t compare two photos. It simply re-measures your face and checks whether those measurements match the template we already have. If they do, we know it’s really you.
This protects you from fraud and helps keep your account secure, while keeping your personal information safe.
