SOC 2 Type II

ISO 27001

GDPR-ready

Built in Europe

Built for the parts of auth that are hard to get right

Token security

Bearer-bound tokens (DPoP) with non-extractable keys, so a stolen token is useless to an attacker.

Session control

Revoke a single session, all others, or every device, from the frontend SDK or the Management API.

One platform

Number intelligence, verification, and anti-fraud live next to auth, not in a separate product.

European by default

Your authentication data stays in Europe, under EU law, with no exposure to the US CLOUD Act.

Where Prelude goes further than Auth0

Capabilities that ship natively with Prelude and that Auth0 either handles only at the management layer, supports partially, or leaves outside its product.

MAU model

Steep tier jumps

A stolen token stops being worth anything

Prelude binds access tokens to the client that requested them using DPoP (RFC 9449), with keys that can't be extracted from the device. If a token leaks, it can't be replayed somewhere else.

Revoke exactly the session you mean

Sign a user out of one device, every other device, or all sessions at once. List active sessions with device metadata straight from the frontend SDK, no round trip through an admin API.

storia della portabilità del numero

Auth, verification, and fraud on one platform

Number intelligence, identity verification, and telecom anti-fraud run on the same platform as your login flows. Catch SMS pumping and IRSF before they hit your bill, using signals you already collect at sign-in.

Your authentication data stays under EU law

Prelude is a French company with infrastructure hosted in Europe. For businesses and the public sector, that means a sovereign partner instead of a dependency on a US group.

100% European hosting

Authentication data is hosted in Europe and protected by GDPR. No default routing through US infrastructure, and no CLOUD Act exposure on data that identifies your users.

French company, EU jurisdiction

Prelude operates under EU law. Auth0 is part of a US group (Okta), which exposes customer data to US extraterritorial reach regardless of the region you select.

The same MAU model, without the tier shock

Prelude charges per monthly active user, like Auth0. The difference is what happens when you grow: no sharp jump in cost because a handful of extra users pushed you into the next tier.

Prelude

vs Auth0

Same per-MAU model, priced to scale smoothly as your user base grows. You track usage in real time and see costs before they land.

predictable as you grow

Auth0

Per MAU

Also priced per monthly active user, but with steep increases at each tier boundary, where a few extra users can move you into a much higher bracket.

Switching from Auth0

Can I migrate from Auth0 without forcing every user to log in again?

Yes. Prelude has a migration hook that validates and imports existing sessions, so users move over without a forced re-login. You can migrate gradually rather than in a single cutover.

Does Prelude support the standard login methods we already use?

Yes. Prelude has a migration hook that validates and imports existing sessions, so users move over without a forced re-login. You can migrate gradually rather than in a single cutover.

How does token security compare to Auth0?
