Replace passwords/codes with tap-to-confirm identity-first login

Many organizations — from startups to mid-market SaaS and large enterprises — still rely on passwords and one-time codes that frustrate users and enable account takeover fraud; globally roughly 3.0M apps represent a $15.0B addressable market (at an average $5K ACV) that is actively looking for stronger, lower-friction authentication. The operational and support costs of credential reset, plus fraud losses, create a measurable drain on revenue and brand trust that security and product teams are incentivized to fix now. You could build an authentication-as-a-service that replaces passwords and codes with a tap-to-confirm, identity-first login flow built on passkeys/WebAuthn and device-attested FIDO2 primitives, bundled with turnkey web and mobile SDKs, a serverless hosting option, admin console, and adaptive risk signals. Position the product as dev-friendly with client libraries and migration tooling for legacy flows, while offering enterprise features — SSO/IDP integration, compliance logs, and device trust scoring — that justify an average $5K ACV per app. Strengths include clear user experience improvements and alignment with native browser/OS standards; real challenges will be ensuring cross-device compatibility, handling fallback UX for unsupported devices, and overcoming enterprise procurement inertia. This is an attractive moment to enter: native OS/browser support for FIDO2 is expanding, account takeover rates are rising, and developers expect composable, serverless-friendly auth primitives — trends that together raise the market score toward the 92/100 and revenue potential toward 88/100 cited above. To stand out in a medium-competition landscape you must prioritize developer experience, a frictionless migration path from passwords, enterprise-grade compliance, and measurable fraud-reduction analytics; be honest that differentiation requires sustained investment in reliability, platform partnerships, and customer education.
