So there's no "I forgot my password" function in it then? Like where you can reset usually by email, text message, etc. and then make a new password? Being that this app comes from China there may well be a backdoor into it, but probably only GO would know about it. Which they would give to Chinese law enforcement and public security if required.
I never use GO Apps myself, mainly because of intrusive ads and data mining. Like they already know enough about me in China without giving them any more.
