We currently open meetings on seven different accounts. We pass host roles and if they don't need anything else, we leave the meeting. But many times they call again because they do not know how to do some things they need or they lose the host role because they leave the meeting and ask to restart it later, etc, etc, etc.
So you have to open and close to enter another account, dozens of times every day every day.
It benefits us to save sessions with the username and password and open them with an auto login or something even to be able to have them open simultaneously
Something I got with the Vivaldi browser that at least reminds me of username and pass and allows me to easily autocomplete.
But it is not a definitive solution.

and thanks for asking
