- 10 digits takes 6665760 minutes to crack on average
All 3 of these work out to the same number: about 12.5 attempts per second.
So if you use a 5 character _alphanumeric_ passcode (62 character key space), then it would take 62^5 / 12.5 / 60 / 60 / 24 = 848 days to brute force in the worst case (and half that on average). With 6 characters it would take more than a century.
