How it works

JamAuth does two things: it proves the user controls an email, then decides whether they’re allowed. You can use Stripe, a webhook, or nothing at all. Sessions are verified on your domain, so access changes take effect immediately and work across modern browser cookie rules.

WHY JAMAUTH

PRIVACY

JamAuth never becomes your user database. You keep your data model — we handle the gates.

SECURITY

Revoke access without touching user records. No passwords to leak. Smaller blast radius.

CONTROL

Add access enforcement without rewriting your app. Remove JamAuth later without migrating users.
