Authenticate using a DID

In order to obtain a DID and authenticate its holder, MATTR VII must request its holder to provide the DID in the form of a verifiable presentation. The short-lived presentation request is derived from a presentation request template, which defines that the verifier is requesting a DID.

Prerequisites

You need the following in order to proceed with this tutorial:

• Access to the MATTR VII APIs.

• Download the MATTR Mobile Wallet App and have it set up with a PIN.

• Verifier DID for signing messages. This DID must include a non-BLS key type. Refer to Create a DID for step-by-step instructions.

If you’re experiencing difficulty with any of these prerequisites, please contact us.
