Polygon ID is a free-to-use Android application developed by ZKID Labs AG that allows you to create and manage your own self-sovereign digital identity. With Polygon ID, you can prove your access rights and reputation without revealing any of your personal information. The app is an open-source and private by default identity system based on zero-knowledge cryptography (zkSNARK).

The app provides you with the ability to generate private proofs for digital interactions and have access to web3 and web2 services. You can conveniently control your identity with secure authentication using biometrics or a 6-digit PIN and identity recovery with a seed phrase mechanism.
