Prevent my phone from being locked of multiple password attempts

It already happened three times. My Motorola XT890 locked itself from being kept in the pocket trying to guess a password, ending up with the 'too many password attempts' screen and requiring Internet connection to get unlocked via a Google Account.

The problem is that if there's no Internet connection, the system won't offer a standard way of activate it and authenticate, leaving us to a factory reset and some other complicated ways to bypass this problem.

How can I prevent this from happening again? I ask in terms of what I can do when the phone is unlocked and usable.
