We were able to ship MFA, SSO, and SAML for our customers in a fraction of the time. Now, we have improved security and must-haves for enterprise prospects.

Building out MFA, SAML, and phone number authentication with Clerk was super easy. I had a working MVP in just a few hours. Plus, Clerk × Cursor works really smoothly, which was a nice bonus.

CTO, Chasi
Clerk took the pain out of auth for us. Multi-tenant workflows and SSO were surprisingly easy to implement, customization was flexible enough to match our product, and onboarding just worked. It removed complexity we would have otherwise had to build ourselves.
