- Login to Google Plus and click on the 'Gear' at the top right side of the screen. You will now be taken to the settings page, choose 'Google +' at the left.
- Scroll down to 'Huddle' and tick the check box below 'Email'. Doing this ensures that you can use Huddle both on your smart phone and desktop. If you don't want to use Huddle on your desktop, you'd be better off with the default settings.
- Now, change the drop down menu a couple of lines below from 'Anyone' to 'Extended Circles' or 'Circles'. This makes sure that strangers don't start Huddling with you.
P.S. To Deactivate Huddle altogether, just uncheck the boxes below Email and Phone.
