Iphone with no password asking for it?

I just set up my mothers new iPhone 5s for her, and I only set up the fingerprint pass code for her (obviously using her finger). I restarted the phone, and now it's asking for a digit password that I didn't put in and my mother knows nothing about. Do these phones have default pass codes, or is it some random glitch?

It needs a passcode as a backup. Make it a simple four digits.

  • Why does my iPhone keep asking for my Apple ID password? I have a 5c and I'm on IOS8. I went on it today and it just randomly asked for my password. I entered it but nothing happened/downloaded. I was just wondering if it was a glitch or something.
  • My iPhone keeps asking me for my apple I. D password? I changed my apple Id and password. Whenever I go to the App Store from my iPhone it asks for my new password to my new apple id which is good. But at random times when I'm texting or something, the old Id will pop up and asks me to type in my password. I don't know how to fix this but it's driving me crazy. :/
  • IPhone keeps asking for Apple ID password? I charged my iphone 4s with iOS 7 from dead battery, and when i turned it on and unlocked it, it came up with the pop up to enter the apple ID password for my iCloud account. No matter how many times i entered the password or pressed cancel, it would keep popping up a couple of seconds later. I tried restarting the phone, but now its popping up with the same thing asking for my Facetime account. It is annoying because i can't use my phone. Any solutions?
  • Iphone 5c asking for password? Just got the iphone 5c thanks to a GREAT deal with Sprint (my first iphone and I LOVE it!). One thing that annoys me, however, is that anytime I want to download something from the app store, it requires me to enter my password. Every. Single. Time. Quite annoying if I just downloaded something 30 seconds ago. I can't seem to disable it, though. Anyone have an idea?
