Much more convienient than a passcode with a little less security. I'd still use it unless I was a CIA agent.

How is it less security though? You don't have to follow someone for very long with a high zoom camera before you can get their passcode and that is a lot easier than duplicating their fingerprint. And yeh it is much much more convenient.

Do you inadvertently leave your pass code lying around in random placed all day long? How often can you change your fingerprint?

The Touch ID is less secure because you can force a person to put their fingerprint to unlock their own phone. Forcing the passcode out of someone can prove more difficult and the phone will wipe itself after 10 tries (if you have that feature enabled).

I could steal your phone and manage to unlock in the process by taking your hand and unlocking the phone before walking away, somewhat more difficult to do with a passcode.

You'd still have to force the correct finger, and Touch ID requires a passcode after five incorrect tries.
