ArcGIS Portal Authentication with Biometrics #26
Description
It would be very convenient to Authenticate against your Portal with Biometrics. I think this could be accomplished as a thin wrapper over the AGSPortal in workflow similar to this:
- instantiate an AGSPortal with url and login required.
- After the user logs in for the first time, make sure a credential cache is stored in Keychain.
- Next time the user needs to login, Biometrics can be used using LocalAuthentication to check if fingerprint/face ID is supported and enabled on the device with LAContext.
- If the touch ID/face ID authentication was successful, fetch the credentials from the Keychain and login, otherwise allow the user to try again or sign in manually with their username and password.
