InMTH app, Maximum engine speed lock password protected, unlock in system settings

Did you already set a password and forget it?

There is a way to recover it, but it takes a bit techy skill to do so.

I never set a password. This happens on some engines, not all.

The password is universal to the app and not engine specific. If you set a password it applies to the app as a whole for all engines and features that are password protected. There is only one password and different engines and/or features cannot be locked out using different passwords.

I have found that once a password is set, removing and changing it are difficult to do, but not impossible.
