About iPhone Passcodes
The exact behavior of the iPhone depends on its configuration when one forgets the passcode. By default,
there is not a passcode at all.
However, Apple notes the following regarding forgotten passcodes:
If you repeatedly enter the wrong passcode, your iPhone will be disabled for longer intervals before you can try again. After too many unsuccessful attempts, you won't be
able to try again until you connect it to the computer with which you last synced it.
Note: You can configure your device to erase itself after ten consecutive incorrect password attempts. This setting is off by default. It can be turned on by tapping Settings > General > Passcode Lock.
If you cannot remember the passcode, you will need to restore your device using the computer with which you last synced it or iCloud. This allows you to reset your passcode and resync the data from the device (or restore from a backup).
