A fellow iPhoner asked me what security you get from using the fingerprint scan when a thief can catch someone inputting their numeric passcode, steal the phone, restart it and enter that code to get into the phone (which is true). What am I missing here? That it minimizes the number of times you have to enter your code hence thieves have fewer opportunities to catch someone entering their code?

Nope - in any secured system, if the thief knows your password / passcode, they can get into your device. The fingerprint scanner is a convenience mechanism in its current state.

Michael’s totally right. Anyone who knows your numeric passcode can get in and your finger is unnecessary.

For greater security, choose “Custom Alphanumeric Code” and select a long, difficult-to-guess alphanumeric code like “HowToDiagnoseDiarrheaInMartians987”.

This site helps you determine how strong your chosen password is.

Got it. Thank you all. Rafagon- I think I'd like to use your "suggested" alphanumeric code!! Lol

Oops—I neglected to mention how to tell iOS you want a custom alphanumeric code instead of a numeric one—just in case your fellow iPhoner doesn’t know the steps.

These steps were cut and pasted from this article.

In addition to what Michael said, you can remotely erase the phone or put it in lost mode if it's stolen, which will lock out a thief even if they know your passcode.

Had to do that once when my wife's iPhone 5 was stolen. I went to find my phone on my PC for several hours and the phone wasn't ever turned on so I left the instruction to wipe it when next it signed onto the network. I got email notification two days later that the phone had been turned on and wiped out a few minutes before the email was sent.

I believe with Lost Mode, the thief could unlock your iPhone if they know your passcode.

That’s what the first bullet point on step four on this Apple Support Document seems to suggest, as well as the following paragraph a little below that:

It is just for your ease, not for making your security better. :S

It is for both. You put your password in fewer times, which decreases how often people can spy on you while you input your passcode. It also secures purchases and certain apps.
