Better Authenticator
Better Authenticator by Yashesh Bharti rebuilds the TOTP authenticator as an iOS keyboard. The code lives above the letters, one tap to paste, no app switch, no thirty-second sprint. The product is the removal of app-switch fatigue.
PulseProof by Yashesh Bharti handles the harder question: not "who are you" but "are you a real human, right now". On-device rPPG liveness in under two seconds, signed verification token, no biometric data leaves the device. SOC 2 Type II, GDPR, HIPAA aligned.
03Where this is going
AI-agent authorisation
Authentication for human users is well-trodden. Authentication for AI agents acting on behalf of human users is not. The interesting work is at that boundary: a signed token that says "a real human just authorised this action", freshly minted, scoped to a specific action, and revocable.
04FAQ
Authentication engineering questions
Who is Yashesh Bharti as an authentication engineer?
Yashesh Bharti builds authentication infrastructure that removes a specific tax users pay every time they prove who or what they are. Two products in production today: Much Better Authenticator (TOTP as an iOS keyboard) and PulseProof (on-device rPPG liveness with signed verification tokens).
What is Much Better Authenticator?
An iOS keyboard that surfaces TOTP codes above the letters. Tap once to paste the current code directly into any login field. No app switch, no thirty-second sprint, RFC 6238 compliant.
How does Yashesh Bharti think about AI-agent authentication?
Authentication for human users is well-trodden. Authentication for AI agents acting on a human's behalf is not. The signed PulseProof verification token gives a relying party a freshly-minted, action-scoped, revocable assertion that a real human just authorised an agent's action.
