Hi HN! I’m one of the founders of Stytch (https://stytch.com/?utm_source=social&utm_medium=hackernews&...). We provide developer APIs and SDKs that make it simple to embed passwordless authentication in your apps. Today, we support email magic links, SMS and WhatsApp passcodes, and one-click user invitations.

We’re working on adding more features like session management, WebAuthn, OAuth support, QR codes, and more in the coming months. Our docs and guides make it really simple to set up authentication for a new app or add additional features to an existing app.

Here’s more on why we’re building Stytch: https://stytch.com/blog/why-stytch/?utm_source=social&utm_me... Sign up today and try it out: https://stytch.com/?utm_source=social&utm_medium=hackernews&...

Would love any feedback and questions!
