zoom desktop client.

Hello Vulcy!
If you have downloaded the Desktop Client/App, you don't have to sign into the web browser anymore; simply sign in on the opening/welcome screen of the app. 

If you have an existing Zoom account (that you already use in a web browser), you can use that same account here.
💡Bonus: If you use Apple, Google, Facebook, or have an education or public service account (SSO - Single Sign On), you can get logged in without having to remember an additional password! And if you have several accounts (for example, a personal account using Google and a work account using Microsoft), you can log into both and SWITCH between the two.
