Support for Biometric Authentication #5

Closed LinusU closed 4 years ago

LinusU commented 5 years ago

Any plans to support biometric authentication?

On iOS this can be implemented by sending the biometryAny or biometryCurrentSet SecAccessControlCreateFlags, the system will then handle showing a TouchID/FaceID prompt to the user when the value is read back.

On Android this can be implemented with a .setUserAuthenticationRequired(true) call together with BiometricPrompt (using androidx for backwards compat). Here is an example from Google, and here is a guide on getting the compat lib up and running.

No, but by all means send me a pull request.

LinusU commented 5 years ago

I'd be happy to!

Would you be open to using square/Valet on the iOS side? It's available thru cocoapods so it will be invisible to the end user.

I'll also need support for shared keychain access groups in my application and using Valet abstracts both biometric authentication and shared (local & iCloud) access groups really nicely. It would make the lines of code in this project really few!

Sure, go for it.

@jeroentrappers Hi, have you made something on this? I'm looking for plugin which has Biometric and keychain integration. Maybe you've com up with another plugin which solves this feature? Thanks

LinusU commented 4 years ago

I ended up just making some quick bindings to the BioPass library since I needed access from native code as well and it was an easy and clean solution:

If I had the time I still think it would be nice to get it in here :)

Was this ever implemented on this library?
