Register new user on test server

New users require registration. This can be done with a claim payload like this by an existing user:

  const vcClaim = {
    "@context": "https://schema.org",
    "@type": "RegisterAction",
    agent: { identifier: identity0.did },
    object: SERVICE_ID,
    participant: { identifier: newIdentity.did },
  };

On the test server, User #0 has rights to register others, so you can start playing one of two ways:

• Import the keys for the test User did:ethr:0x000Ee5654b9742f6Fe18ea970e32b97ee2247B51 by importing this seed phrase: seminar accuse mystery assist delay law thing deal image undo guard initial shallow wrestle list fragile borrow velvet tomorrow awake explain test offer control (Other test users are found here.)

• Alternatively, register someone else under User #0 automatically:

  • In the src/views/AccountViewView.vue file, uncomment the lines referring to "testServerRegisterUser".

  • Visit the /account page.

Create multiple identifiers

Go to /start and create or import a new one. Then switch identifiers on the bottom of the Your Identity page.

Create keys with alternate tools

See this page

Customize Vue configuration

See Configuration Reference.

Scenarios

• Create a new identity as prompted. Go to "Your Identity" screen and copy the ID to the clipboard.

• Go back to /start and import test User did:ethr:0x000Ee5654b9742f6Fe18ea970e32b97ee2247B51 with this this seed phrase: seminar accuse mystery assist delay law thing deal image undo guard initial shallow wrestle list fragile borrow velvet tomorrow awake explain test offer control (Other test users are found here.)

• Go to "Your Contacts" screen and add the ID you copied to the clipboard, and hit "+" to add them.

• Click on the "Registration Unknown" button and register that person to be able to make claims as them.

Clear data & restart

Clear cache for localhost, then go to http://localhost:8080/start (because it'll generate a new one automatically if you start on the /account page).
