Android Xamarin fingerprint get unique id to set username

Question

I am new to xamarin.

In my first project I will just create a fingerprint login and say hello to the logged-in user:

So in android I have 3 fingerprints:

user1 = **alex**
user2 = **steven**
user3 = **sam**

for now iam using this fingerprint plugin

is it possible to get an unique id which fingerprint is used?

so if alex put his finger on the sensor I get as a result a unique id = 123456789 (every time user alex put his finger on the sensor)

at the end i will output the current authentcated user like hi alex or is it possible with another plugin/code?

thanks
