How PTERI is applied in real systems
This section shows how PTERI’s single trust model is applied across different scenarios, without changing primitives or introducing special cases.
Each use case uses the same flow: Wallet → Signature → Verification → Outcome
Traditional SaaS login relies on:
Passwords
Email resets
MFA add-ons
These increase friction and expand the attack surface.
User requests login
Backend issues a challenge
Wallet signs the challenge
Backend verifies and issues session/JWT
There are:
No passwords to store
No recovery emails
No OTP codes
Login becomes a cryptographic proof of authority.
