Keystone — Free Auth UI Kit
A complete authentication flow, documented end to end.
Keystone is a free Figma UI kit covering the full authentication experience for modern products — Login, Sign Up, Forgot Password, Reset Password, and Verify Email (OTP).
Unlike most free auth templates, Keystone doesn't stop at the happy path. Every screen includes documented fail states — empty fields, invalid formats, incorrect credentials, server errors, expired codes — built on a Primitive-to-Semantic design token system shared with Ouroboros Studio's other kits, Vantage and Domus.

- Anyone needing a credible, system-driven starting point for auth screens Screens Included
