Default Keys

Your default key is automatically created when you sign in or register, and it's always ready to use.

What is a Default Key?

Your default key is:

  • Automatically created when you first sign in or register
  • Always labeled "default"
  • Ready to use immediately - no setup required
  • Your primary key for signing documents

When is it Created?

For Registered Users

When you complete registration with WebAuthn: - Your account is created - A default key is automatically created - You can start signing documents right away

For Anonymous Users

When you sign in as "ANONYMOUS": - You're logged in immediately - A default key is automatically created - You can start using the app right away

Default Key Properties

Default keys have special characteristics:

  • Label: Always "default"
  • Type: EdDSA (Ed25519) cryptographic algorithm
  • Format: did:key identifier
  • Cannot be upgraded: Default keys cannot be bound to a did:web DID
  • Cannot be deleted: Your default key is permanent
  • Always present: Every user has exactly one default key

Using Your Default Key

Your default key works exactly like other keys:

  • Sign documents: Use it to create proofs on any document
  • Appears in proofs: Shows as the verification method in signed documents
  • Can be selected: Choose it when creating proofs
  • Shows in activity: All actions with your default key are logged

When to Use Default vs. Custom Keys

Use your default key for: - General document signing - Quick testing - Personal documents - Getting started

Create custom keys for: - Production use cases - Specific projects - Key rotation - Upgrading to use your DID

Limitations

The only limitation of default keys is:

  • Cannot be upgraded: If you want to use your user DID, create a custom key and upgrade it

Everything else works the same as custom keys!
