# Passoot

*/Startups/Passoot*

## Startup Overview

This authentication layer operates as a headless API that binds biometric passkey events directly to an application's existing identity session tokens. Developers integrate the service to handle the cryptographic handshakes of WebAuthn without replacing their current user management infrastructure. The system processes the biometric input and returns a seamlessly verified session state.

Engineering and security teams face massive friction when migrating legacy password-based accounts to modern passkeys. Building custom WebAuthn deployments requires specialized cryptographic expertise, while platforms like Auth0 and Stytch force adoption of their entire identity provider ecosystems. This service bypasses the lock-in by functioning as an invisible, modular add-on that upgrades existing token architectures.

By remaining completely headless, the platform separates the biometric validation step from the underlying user database. The billing model breaks from industry standards by charging strictly per successful biometric authentication, rather than per monthly active user. This exact-usage pricing makes passkey adoption viable for consumer applications with massive, infrequent login volumes.

## Startup Founding Hypothesis

## Startup Offer

**Proof**:
- Targeting a complete elimination of SMS 2FA expenses for consumer application developers
- Aiming to reduce WebAuthn engineering integration time from weeks to under a single afternoon
- Designed to achieve zero account takeovers for users actively secured via our biometric binding
**Tiers**:
- Name: Developer Sandbox · Price: Free up to ~1,000 successful auths/mo · Inclusions: Full API access, unlimited test-environment passkey registrations, and community support for prototyping headless integrations.
- Name: Production Scale · Price: ~$0.04–$0.08 per successful authentication · Inclusions: Unlimited biometric registrations, active token-binding to live sessions, and standard SLA aimed at consumer application traffic.
- Name: Enterprise Volume · Price: ~$0.01–$0.03 per successful authentication · Inclusions: Custom rate limits, dedicated Slack channel support, and committed uptime targets for high-volume identity providers.
**Guarantee**: Passoot guarantees valid passkey assertions will bind to your existing session tokens in under 300 milliseconds; if API uptime drops below 99.9% in a billing cycle, you receive a full usage credit for that month.
**Business Function**: ProvideService
**Objection Handlers**:
- We already use Auth0 for identity: Passoot is designed to run headless alongside your existing Auth0 deployment, handling only the biometric verification and passing the validated assertion to your current session.
- WebAuthn is an open standard we can build ourselves: Building custom WebAuthn requires managing device fragmentation, cross-device sync, and cryptographic state; we abstract this maintenance into a simple API call.
- What happens when a user loses their phone: Passoot handles the biometric assertion layer only; your core identity provider retains full control over fallback authentication methods like recovery codes or email links.
- We do not want to pay per user for an authentication feature: You do not pay for registrations or dormant users; Passoot bills strictly per successful login event, aligning your costs with active platform usage.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- A 14-day staging environment integration pilot aiming to validate sub-300 millisecond session binding speeds and confirm seamless handoffs to the client's existing identity provider.
- A 60-day limited production rollout to 5 percent of a consumer application's user base, aiming to measure the exact reduction in SMS 2FA payload volume and the successful registration rate of new passkeys.
**Target Metrics**:
- Target: 100 percent elimination of SMS 2FA delivery costs for active biometric users
- Target: Under 300 milliseconds for biometric assertion to existing session token binding
- Aim: Reduction in WebAuthn engineering integration time from 3 weeks to under 4 hours
- Target: 0 account takeovers for users actively secured via biometric binding
**Target Case Studies**:
- Target: A mid-sized consumer fintech application (VP of Product) proving the complete elimination of SMS 2FA delivery expenses by replacing text-based codes with Passoot's headless biometric binding.
- Target: A high-volume e-commerce platform (Lead Authentication Engineer) validating a reduction in checkout login friction by integrating passkey assertions directly into their existing Auth0 deployment.
- Target: A consumer SaaS provider (CISO) demonstrating zero account takeovers among user cohorts that transition fully to device-bound biometric logins handled via the Passoot API.
**Testimonial Targets**:

- Severity: existential · Description: Incumbent identity providers like Auth0 natively bundle headless passkey binding into their core session tokens for free. · Mitigation Status: unmitigated
- Severity: high · Description: Apple or Google restricts WebAuthn APIs to prevent third-party headless services from binding passkeys to non-native session tokens. · Mitigation Status: unmitigated
- Severity: moderate · Description: Enterprise customers reject the strictly per-authentication pricing model due to unpredictable monthly costs compared to flat-rate subscription tiers. · Mitigation Status: in-progress
- Severity: moderate · Description: Session binding vulnerabilities allow malicious actors to hijack tokens during the handoff between the existing identity provider and the biometric event API. · Mitigation Status: in-progress
