Excellent I use gauth to provide 2FA for ssh logins  su/sudo attempts  Gmail  aws... and I also use it for work. It's practical security done  seemingly  very well. My only complaint is a UI problem. I have a lot of keys and the existing display options have no company option. It's frustrating to scroll through the list  especially when we could easily have a font size option as well as compact themes to reduce whitespace.
