Developers. Always.

We built the authentication platform we wished we had. Passage gives you everything you need to build the best authentication experience your users have ever seen with the fewest story points you can imagine.


How it works


Add Passage Element to your frontend

Elements are designed to work with any frontend framework and look great for every user on every device.


Authorize requests with a Passage SDK

We provide SDKs to make it easy to check session tokens and identify which users are making requests.


That's all!

Why spend weeks on what could take minutes? At least that's what we always say.

User Experience

With Passage, users sign in using the biometrics already built into their devices (e.g. Touch ID, Windows Hello, etc). When biometrics aren't available, Passage falls back to magic links to keep friction low and conversion rates high. No apps or extensions required. All native, and all in the spirit of simplicity.
