Once you have created your Gatherly event, you can set a mandatory password for everyone coming to your event.
First, click the "Edit" button on your desired event.
Make sure that you're on Step 1.
Now, you can choose to enter a password for your event.
To save your changes, click the "Save" button in the top right corner of your screen.
You can change or remove this password up to 5 minutes before the event start time.
Everyone attempting to log on to your event will be required to enter this password, so be sure to send the password to attendees ahead of the event!
Once the event is underway, the password can not be changed or removed.
