Show HN: I built ephemeral authentication – no tokens, just vanishing proofs

Show HN: Ephemeral Auth – Authentication without tokens using vanishing proofs I built a React authentication library that eliminates tokens entirely. Instead of hackable JWT tokens that last for hours, it uses ephemeral cryptographic proofs that vanish after each request. *The Problem:* Token theft gives attackers hours of access *The Solution:* Single-use sessions that self-destruct after one action \it is on npm on these link https://www.npmjs.com/package/ephemeral-auth-react https://www.npmjs.com/package/ephemeral-auth-react *npm:* poof-auth-react *How it works:* 1. Request ephemeral challenge (one-time math problem) 2. Solve challenge → get ephemeral session 3. Session vanishes after use - hackers get nothing! *Features:* - No tokens to steal or manage - Quantum-resistant cryptography - Simple React API - TypeScript support Perfect timing given recent token breaches and supply chain attacks. Would love feedback from the HN community! Demo: https://www.npmjs.com/package/ephemeral-auth-react https://www.npmjs.com/package/ephemeral-auth-react
