Why are some invitees required to login to a meeting?
By default, people who are invited to Vyew do not need to login, register, or even have a Vyew account.
When inviting people to a non-scheduled meeting, if you select “No” when asked “Allow user to share with others?”, that attendee will be required to enter their email address. They’re not required to register or already have a Vyew account of their own, but just to enter the email address to which the invitation was sent. This verifies that the person who received the invitation is the person joining.
