  • True, one person needs an account. You used to be able to do Jitsi - and before it other webrtc calling solutions - with no account at all but now Jitsi also needs the first host to sign in.

    But Signal calls, every participant must have a Signal account. The others, I can invite people to join with no account.

    “Browser tech”? Just the fact you can make it work from a browser without needing to install anything else. Again, Signal isn’t set up for that kind of thing. It’s just designed and extended from a different use case.















  • You are not the only one able to execute code under your user’s name. A normally installed program, running under your directive as user, can run other commands under your authority as user.

    But it can’t run as root. You can run things as root via sudo, when you prove your identity as yourself - with the password - rather than another program operating in your name.

    Passwordless sudo I think could be exploited e.g. by writing a script and passing it to bash.

    (Or, as another reply pointed out, it provides a barrier against moderate malice of a passer-by or a ‘friend’ temporarily using your computer.)
