Standard OAuth 2.0 / OIDC. No sensitive data to store. No liability. Your users verify once — CAGE handles everything after that.
CAGE never shares government IDs or biometrics with you. You receive a signed token confirming age — nothing more.
If your platform supports Sign in with Google, it supports CAGE. One OAuth flow, two age tiers: 18+ and 21+.
The CAGE browser extension passes verified tokens automatically on return visits. Zero friction for your users after the first time.
We're onboarding a small number of launch partners. Drop your details and we'll be in touch.
