If you keep getting unexpected emails informing you how to obtain a new password, they are probably being triggered by other people attempting to log on to TrailWise.

Your login name may be something just a bit too obvious, like 'fred' or 'honda'. People may attempt to use names like that, either trying to log on illicitly, or in all innocence because they themselves used e.g. 'fred99' and forgot. It's in your own interest to make your login username hard to guess. You can change your username using the features under 'My Account / My details'.
