Introduction
What is Paspo ID?
Paspo ID is a universal biometric authentication platform. Users register once in the Paspo ID app and can then sign in to any connected service using Face ID, Voice ID, or a push notification — no passwords, no SMS codes, no friction.
Biometric auth
Face ID and Voice ID are processed on-device. Biometric data never leaves the user's phone.
One app
Users manage every connected service from a single Paspo ID app.
SIM protection
Accounts are bound to the user's physical SIM card, on top of biometrics.
One tap
Instant login to any connected service, from any of your platforms.
Integration SDKs
Paspo ID ships an SDK for every platform you need to authenticate users on. All source is public on github.com/paspoid.

What integration looks like
Every platform boils down to the same shape: your app calls the SDK, gets back a one-time authorization code, and your server exchanges that code with Paspo ID for the user's verified data. Two things always stay on your server, since they're the basis of the flow's security:
- Generating the one-time nonce the SDK signs.
- Exchanging the authorization code for user data after sign-in.
