2.3 Identity & Authentication
PTERI replaces traditional authentication mechanisms entirely.
There are no:
- Passwords
- SMS OTPs
- Authenticator apps
- Static API keys
The new model
Authentication becomes a challenge–response signature.
- A system issues a challenge
- The wallet receives the challenge
- The user approves via biometrics
- The wallet signs the challenge
- The backend verifies the signature
That’s it.
There is no secret to steal and no code to replay.
Who this works for
The same model applies to:
- End users
- Admins
- Internal services
- Machines
- AI agents
Identity is no longer tied to a UI flow — it is tied to authority.
