AUTHENTICATION FOR CONSUMER APPS
Build authentication that feels like a seamless part of your app
APIs, SDKs, and pre-built UI with everything you need
to authenticate users and protect your application from fraud and abuse.

Auth is easy to implement, but hard to get right. Stytch gave us complete infrastructure to secure and scale auth with best practices built-in.
