On password prompts (e.g. from sudo), Termius should not display the input when using MOSH.
I am using Termius in MOSH mode, with tmux to have a persistent local session. When I use sudo in my tmux pane, Termius will echo the characters of the password. On a slow connection, the password can be accidentally revealed to an attacker if the screen is visible. Please try to detect password prompts and do not echo the input in this case!
