I am looking for a type of software for a specfiic use case. Is there a software that can email my clients a link or a one time code to remote in to my setup workstation/computer? The simpler this software the better. I just want to simply install the software on a computer and when my clients ask access I want to send them a link that allows them to access my computer through their browser for that one session(if they have to download an application themselves it's not a deal breaker but not preferred). It would also work if its a software and one time code or something of the sort. The only thing that is the most important is that they can only access this computer for one session. I do not want them to have continued access. Just the once that they request it.

I don't have time to develop this software, this is simply for testing purposes and don't want to put in too much time. it doesn't have to be free but the cheaper the better.

I know about google remote access and other tools like team viewer but they allow the user continues access and user need to register there. I would like the software to not need registration and just use a one time link or code.

Please point me in the right direction. Thank you.
