Iphone 5s finger print scanner?

Can you use a numeral passcode for the 5s or does it have to be a fingerprint?

It can be a numeral passcode as well. Just go to settings, General, passcode lock, then change your passcode to whatever you want. Hope this helps.

You can do both, just passcode, or fingerprint.

If doing fingerprint then make sure you use the same thumb for all 4 options, etc, some people use diff fingers and thats not as accurate, you should use the thumb 4 diff times, etc, when setting it up.

Also you can use ordinary password or drawing as other smartphone
