Tessio is an age and identity verification API built on the EU Digital Identity Wallet. Most age assurance today means uploading an ID document or taking a selfie. That solves the regulator's problem by creating a data protection one, because you then hold identity data you have to secure,...

  • Wallet-native age checks
    Proves 18+ (or any of thirteen age thresholds) from the EU Digital Identity Wallet. The user approves the request on their own device.
  • No personal data received
    The credential we request carries age booleans only: no name, no date of birth, no document number, no photo. There is nothing to store or breach.
  • One API call
    Start a check with a single REST call, get back a link or QR code, receive the signed result on your webhook.
  • Signed webhooks
    Results delivered with an HMAC-SHA256 signature and timestamp, so you can verify authenticity and detect replays.
  • Both EU credential formats
    SD-JWT VC and ISO mdoc, the two formats the EU wallet ecosystem uses. The verifier underneath passes the OpenID Foundation conformance suite in both.
  • Sandbox included
    Integrate and test end to end today; checks complete in about two seconds against the sandbox.
  • Open source core
    The verifier library is Apache-2.0 on NuGet, so you can read exactly what the crypto does before trusting it.
  • EU hosted
    Runs entirely on EU infrastructure (Finland). Data never leaves the EU.

Questions & Answers

As answered by people managing StackSource and Tessio.

What makes your product unique?

Tessio's answer:

Tessio verifies age from the EU Digital Identity Wallet instead of collecting documents or selfies. The credential it requests carries age booleans and nothing else: no name, no date of birth, no document number, no photo. That means there is no identity data to store, leak or audit, and it is a property of the protocol rather than a promise, so you can verify it yourself. The verifier underneath is open source and passes the OpenID Foundation conformance suite for OpenID4VP 1.0 HAIP verifiers in both EU credential formats.

Why should a person choose your product over its competitors?

Tessio's answer:

Most age verification vendors solve the regulator's problem by creating a data protection one: you end up holding ID documents or biometric data. Tessio asks a narrower question and receives a narrower answer, a signed yes or no. For platforms under the UK Online Safety Act, the EU Digital Services Act or gambling licences, that removes the breach surface and most of the GDPR overhead instead of managing it. And because the verification core is open source, a technical reviewer can check the claims before ever talking to us.

How would you describe the primary audience of your product?

Tessio's answer:

Compliance and product teams at age regulated platforms in the EU and UK: iGaming operators, nicotine and alcohol e-commerce, dating and social apps, and the platform providers that serve them. The integration is a REST API with webhooks, built to be wired in by one developer in an afternoon.

What's the story behind your product?

Tessio's answer:

Tessio is built by a small studio in Stockholm (Triple Down AB). The starting point was a regulatory collision: age checks are becoming mandatory across Europe while the usual methods, document upload and face scanning, create exactly the data protection risk the same regulators punish. The EU Digital Identity Wallet made a third way possible for the first time: a credential that proves an age threshold and contains nothing else. We built the verifier, open sourced it, ran it through the OpenID Foundation conformance suite, and put a hosted API on top. It is early and access is invite only, and the site says so plainly.

Which are the primary technologies used for building your product?

Tessio's answer:

.NET and ASP.NET Core, PostgreSQL and Valkey, a Next.js dashboard, all running on EU infrastructure. The protocol layer is OpenID4VP 1.0 with SD-JWT VC and ISO 18013-5 mdoc credentials. The verifier library, Tessio.Verifier, is Apache-2.0 on NuGet.
