With Outdid, you can verify your identity without sharing your personal data Protect your privacy without losing comfort Did you know that if someone has a photo of your ID document, they can impersonate you, and sometimes even incur debt on your name? When you verify your identity online, this is exactly what you always send - a photo of your ID. Unless you’re using Outdid. Leveraging novel privacy technology, Outdid allows you to finish your ID verification, but without sharing any personal data about you, or photos of your documents. Nobody sees your data, not even Outdid. For example, if a website wants to know that you are over 18, this is exactly what they’ll get - not your passport, not even your name. Keep the app after you use it, because next time a website which uses Outdid asks to verify you, you can complete the verification in one click. How’s that for convenience?
