Require email verification to book appointments in Google Calendar

When using appointment scheduling in Google Calendar, you can now opt to have users verify their email before booking an appointment. When enabled, the user must be signed into a Google account or validate their email address using a PIN code to complete the booking. 

This setting is off by default and is “sticky”. This means that if you turn it on or off, the configuration will be saved for any new appointment scheduling series. We hope this feature helps ensure you’re protected against potentially malicious actors.
