Is this normal ios funtionality for fingerprint and keystore?

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?

this.keychain.get(userName).then(result =>
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.
