# Signup Flow CRO

Production-grade signup and registration optimization framework covering authentication strategy, field reduction methodology, multi-step flow architecture, SSO implementation, progressive profiling, credit card requirement analysis, post-submit experience design, and mobile-specific registration patterns. For post-signup onboarding, use onboarding-cro. For lead capture forms (not account creation), use form-cro.

## Clarify First

Before optimizing the signup flow, settle the inputs below. When one is missing or vague and would change the result, ask about it; when it wouldn't, use a sensible default and say which one you used.

- **Flow type:** free trial, freemium, paid, or waitlist (determines friction tolerance and minimum field set).
- **B2B or B2C:** B2B tolerates more fields; B2C needs minimal friction (sets SSO priority and field count).
- **Current fields + completion rate + drop-off:** baseline and the friction point to cut (each removed field ~+10%).
- **Data truly needed before first product use:** separates must-have fields from those to defer or enrich (the "Before First Use" test).
