Adaptive Auth UX SDK
Build a developer SDK and hosted service that lets apps offer passwords, passkeys, and email fallback in one adaptive authentication flow. The value is fewer support tickets, better login completion, and less user frustration than rigid magic-link-only systems.
Why this matters
You removed passwords because they created reset requests, or you inherited a magic-link flow from an auth vendor. Now users are stuck waiting for email, switching devices, opening the wrong browser profile, or restarting a session that expired mid-login. The people most affected are power users with password managers and anyone using privacy-focused setups, but everyday customers also get confused when email is delayed. Existing tools often force a single login philosophy instead of matching the situation. What you need is a flexible login layer that keeps security strong while letting people finish authentication with the least friction possible.
- · Built for SaaS teams, indie developers, and product-led startups that currently use email OTP or magic-link login and see support or conversion problems..
- · Most likely monetization: SaaS subscription.

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Auth buyers may choose established identity platforms even if UX is worse because procurement favors incumbents.
- 2Passkey adoption may remain too low among end users, weakening the benefit of a multi-method approach.
- 3The product may be seen as a UX layer rather than essential infrastructure, limiting budget and urgency.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Discussion participants repeatedly criticized email-only login, especially when links arrive late, open on a different device, or replace a perfectly good password-manager workflow. Several commenters explicitly asked for passkeys or password support alongside email codes. One builder admitted they removed passwords to cut support load but then recognized the resulting frustration. This points to a practical market need for adaptive authentication rather than single-mode login.
