More than sign-in.
Dazr Identity also tells your app which organisation a person acts for, and whether it is real.
Organisations prove who they are with a qualified signature or seal, a company extract or a code to the registered office. Your app sees the result in the token.
The business register, the ID and live selfie of the representative, and sanctions and PEP screening, for €25 excl. VAT per organisation.
A live photo of the ID and a selfie, with sanctions screening, for €1.50 excl. VAT per person, valid for 12 months.
Owners and admins can require passkeys for everyone in their organisation, in every app that asks for their organisation.
A signed report for every verification, as PDF and as JSON your auditors can check.
Your app hears about new verifications, changes and new sanctions hits as they happen.
Switching from Auth0.
Dazr Identity is standard OpenID Connect, so most apps change only their configuration.
In Dazr Identity, open Developers under your organisation and add your redirect URIs. You get a client ID, and a client secret for web server apps.
Point your OpenID Connect library at https://identity.dazr.eu. If you use an Auth0 SDK, use a standard OpenID Connect library instead; the guides below show how.
At a person’s first sign-in with Dazr Identity, match them to their account once by email (Dazr only issues verified addresses), then store the Dazr sub as the key.
Show both sign-in options while people switch, and remove the old one when you are ready.

Questions about switching.
Is Dazr Identity free?
Yes. Sign-in costs nothing, for every app and every user. You pay only for the verifications you ask for: €25 per business verification and €1.50 per identity verification, excl. VAT.
Where is the data?
Dazr is an Italian company, and Dazr Identity runs on servers in the EU, in Germany. Accounts and records are encrypted at rest.
Do my users need a new password?
No. People sign in with a passkey, a one-time code sent by email, or their Google or Microsoft account. There are no passwords to manage.
Can my app keep its own user database?
Yes. Dazr Identity signs people in and tells your app who they are. Your app keeps its own users table, keyed on the Dazr sub, which never changes for a person.
Which frameworks work with it?
Any standard OpenID Connect library. Step-by-step guides cover Auth.js and Next.js, WordPress, Laravel, Supabase, Django, Node.js, ASP.NET Core, Spring Boot and Keycloak.
Try it in your own app.
Register an app in a few minutes. While it is in testing, localhost redirect URIs work too.
