A Foursquare tweet revealed that "All Foursquare is now defaults to HTTPS."
"All of foursquare is now https! (For non-nerds: this means foursquare is even more secure)," reads the tweet.
The company tells us that this means not only the main website which is less important for Foursquare usage, but also the mobile site and most importantly, the clients. "We're moving to HTTPS proactively to increase the security of all Foursquare accounts," PR Manager Erin Gleason says.
