TouchID / Fingerprint exposed through SDK


Hi, I read in your Aug 7, 2016 blog post that you’ve got the native code in place for TouchID but not in the SDK. I don’t want to brake out of Expo so I just want to make 100% sure I did not miss you guys adding this to the SDK. Any help on the best way to tackle this would also be great.


hello! you can check out and example of using it here:

we haven’t documented in our official docs yet because we intended to create a wrapper so there is a single API on both platforms. we might just go ahead and document the current API and add a layer on top of that later on.


For others looking at this, here is the api ( :

  • hasHardwareAsync

  • isEnrolledAsync

  • authenticateAsync
