- Method for iOS 6.1
- Method for iOS 6.1.3
- Method for iOS 7.0(.1)
- Method for iOS 7.0.2
Bruteforcing
The passcode can also be brute-forced if the device is jailbroken, and the passcode is simple (four digits). It takes under 20 minutes to crack a 4 digit numeric passcode, this is the standard passcode for many users.
| Passcode length | Compexity | Time |
|---|---|---|
| 4 digits | numeric (0-9) | 18 minutes |
| 4 digits | alphanumeric (a-z & 0-9) | 19 days |
| 6 digits | alphanumeric (a-z & 0-9) | 196 years |
| 8 digits | alphanumeric (a-z & 0-9) | 755 thousand years |
| 8 digits | alphanumeric, complex (a-z & special characters & 0-9) | 27 million years |
