Zoom is also now requiring passwords for meetings started by entering a meeting ID since those are relatively easy to guess and hack.
That means that if you're used to joining a meeting just by entering the meeting ID, that won't work.
Just realize that means it won't be quite as easy as it was before
It also means you'll probably have to spend a little more time making sure the right people have the right password to get into your next meeting, starting today
Otherwise, it won't be just the bad guys who can't join your meeting
