I know its not recommended to save the password in mikrotik WINBOX (as password are stored in clear text form in winbox.cfg in local pc user profile), But we HUMANS love being lazy enough or with weak memory sometimes prefer to save the password and the management PC and sometimes this PC is also shared by some other co-admins/colleagues dueto lack of resources :p
In my opinion, It could be annoying backdoor / password leak issue by WINBOX.
Mikrotik developer should really focus in this section , and encrypt the password using strong hash algorithm. I used it few months back at a friend’s admin PC to fetch the iD password with all details as showed in the image. Just imagine what will happen if it fall into wrong hands …
