“Support Webauthn authentication in the frontend. This will allow use of hardware security keys as well as passkeys. Ideally this should be offered as an alternative to a password, instead of as an MFA method.”

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Developers building secure web applications need WebAuthn/passkey support. No search volume, but demand is rising as passkeys become industry standard (FIDO2 adoption accelerating).
Competition & the opening
Very crowded (9/10). Auth0, Hanko, SimpleWebAuthn, Yubico libraries, Passage by 1Password, and Corbado all offer WebAuthn. The gap: a lightweight, developer-friendly library or service that makes passkey-first (not MFA-second) adoption drop-in simple, with minimal backend changes.
What's hard to build
Hard (7/10). WebAuthn requires careful cryptographic handling, browser compatibility management, and recovery flows (account recovery without passwords). Platform-specific quirks (iOS, Android, Windows Hello) and attestation validation add surface area for security bugs.
Why now
WebAuthn/passkeys now have broad browser and OS support (2024+), but most indie devs still lack drop-in frontend libraries that don't require Auth0/Passage licensing.
How you'd monetize
freemium SaaS ($0 for basic passkey library, $19–49/mo for managed backend + use
