# Signup Flow CRO Optimization Framework

> Conversion optimization methodology for signup flows: low-friction form
> design, modern authentication (passkeys/WebAuthn + social with safe
> fallbacks), NIST-aligned password UX, privacy-respecting progressive
> profiling, and statistically disciplined A/B testing. Code samples are
> illustrative starting points — validate any uplift on your own funnel.

> **On the numbers in this skill:** social-proof counts like "Join 50,000+
> Users" in the templates are PLACEHOLDERS. Only display a count you can
> substantiate — inflated or fabricated figures are both an ethics problem and,
> in some jurisdictions, a deceptive-advertising one. Swap in your real number
> or remove the claim. This skill ships **no** universal conversion benchmarks;
> see "Do NOT ship a universal social-login number" below for why.
