[Touch ID Plugin] Detecting Biometric change on Mobile App
Forge component by OutSystems R&D
Application Type
Service Studio Version
11.10.18 (Build 41212)
Platform Version
11.11.2 (Build 29540)

Developed mobile app which performs face recognition using OutSystems TouchID plugin and it works perfectly.

Business would like any sensitive data stored in local device storage to be cleared/deleted if the biometrics changes on the device (say, someone decided to use different finger for their fingerprint).

The App currently stores sensitive information in the local device storage in a secure manner.

Is there anyway that an OutSystems mobile app is able to detect event if biometrics on the device has changed so that it can performs cleanup activities?


I don't believe this is an out of the box functionality for this component but it is built on the Cordova mobile development framework and I did find some documentation that may help you either modify or build a new plugin with this functionality. 




I hope this helps!


Thanks @Bryan Minton 

Since we are using TouchID (and many more Forge components) in our mobile app, the solution of ditching this in favour of using Cordova directly is not very attractive proposition for us as it will mean we have to pretty much redo big part of the application.

If we knew from the start that these type of events were not supported by the Forge components we have selected, then this approach would have been much feasible for us.

We could extend the TouchID plugin but this means losing supports and upgrades in the future (also, not sure what other hidden challenges this would bring to us).

For now, we have decided to "park" this and look at doing something different in the future.

Thanks for your help.
