Josh Morony blog post on topic of creating Ionic app which will use TouchID feature to verify a user.
If you own an iOS device then you will have likely come across the TouchID feature at some point – it allows you to easily unlock your phone with your fingerprint rather than a passcode. This tutorial will teach how to create Ionic app using this feature.
The TouchID authentication can also be passed by using the passcode for the device. Tutorial then describes what you will need to create app with useful links to other resources if you need to grasp basic Ionic concepts first.
Apart from obvious bits - e.g. how to generate Ionic app and how to create the verification lock screen - you will get loads of example code with explanation. Excellent read.
