I enter my login info and save the option to only utilize my fingerprint ID; however, those options continually default back to entering in all login info. iOS 10.3.1
The logins credentials are enetered, it asks to save a four digit passcode, and if I want to utilize the fingerprint ID. I input all of that and select the remember me option. After about two logins utilizing the fingerprint ID it defaults back to the original login credentials and I start the processs over.
