I'm not sure on the semantics of iPhones, but I know Android requires a password after about 5 failed fingerprint scans. For Android you can also require a password on boot. Does the iPhone not have a similar failsafe, in the event someone is trying to bruteforce the fingerprint scanner? Can that be bypassed?

@phyrrus9 might know.

iOS always requires a passcode on boot, and you can set how often its required (default is always). The passcode itself unlocks the encryption key to the partition holding your data, the phone doesn't ever know it.
