About

Clerk is an authentication and user management company that provides developers with pre-built sign-up, sign-in, and user profile components alongside a complete backend API for identity management. Authentication is one of the most common and most error-prone features developers have to build—Clerk eliminates this by offering production-ready authentication that handles email/password, OAuth (Google, GitHub, etc.), magic links, passkeys, and multi-factor authentication out of the box, reducing what typically takes weeks to implement to hours.
