We had started using cordova and got fingerprint working for ios and android.
Trying to convert it over to ionic. Most of the code was a copy line for line.
After the user logs in store off the password for the login.
this.keychain.set(userName, password, true);
I guess true to for touch Id to get the value out?
password = result
This works, the problem is on ios, it asks for their fingerprint, then it seems to asks for their fingerprint to unlock the keystore ?
If I turn off the touch Id value for the keystore. I for some reason get extra fingerprints after.
Another developer wrote our fingerprint code before we just trying to save it. Might be worth rewriting it for Ionic.
