One time password
 

Thought that this question belongs to this category, but please feel free to move the right place if I misunderstand it.

My problem maybe be a bit weird. I want to use jitsi for practicing languages with some people on the internet, to who I've talked many times but do not physically meet each other. We don't add each other on the apps such as whatsapp, signal, riot.im, and so on. Also all those people I contact do not about tech, though they use mobile apps.

So with this scenario I want to setup password when creating a jitsi meet video conference room. However, I do not have a good idea on how to to share the password so that they can login after giving them the conference room url link. Therefore the only way I can think of is one time password, but I am not sure how to achieve this. That seems to me it's impossible. If it's possible, how can I achieve that securely?

Appreciate any comments and suggestions.

So what means of contact with those people beyond Jitsi do you have?

The documentation is pretty skimpy (read: nonexistent), but I did find this in the FAQ
So it appears that passwords are one-time by default.

The place where people communicate with each other (and practice languages) is a language app where people post some short articles like diary and receive correction or comment about their diary.

Thanks but the one time password I am looking for is more like two participants doesn't exchange or share password directly. For instance, I setup a password in jitsi meet. And I do not need to share the password with another people through app's DM or email. Instead, I want a one-time password a bit like lastpass authenticator where two participants looks up the number provided by the authenticator and input that value when accessing that specific conference room. I think this might be workable, but anyway just to check.

Thanks

It sounds like you want a public/private key pair (each).
What you then do is come up with a passwd for Jitsi and encrypt it with their public keys and send it to them.
They then decrypt it with their private key and there you go :)
