Affected device: All tested devices (2 laptop 1 desktop)
Operating system: Windows 10 Pro/Home x64
Part of Prey not working: Prey Configurator
While performing a fresh install of Prey (in this case version 1.7.5-x64) the "Prey Configurator" throws an error on the input of a password containing certain special characters. I have confirmed this with the "Ampersand" ( & ) character (screenshots below) and later also with the "Closing Parenthesis" ( ) ) character (no screenshot of this included).
It may valuable to note that this issue occurs both on when trying to log in as an existing user, and when trying to sign up as a new user, also it is limited to the Prey Configurator and the same input is accepted in the browser control panel and Android mobile app.
