X (née Twitter) rolled out audio and video call support to all users this week, a feature previously limited to those who pay for verification. But there's one pretty glaring issue with that: The option is enabled by default, which means that anyone you follow can now make an audio or video call to you and — even more worrying still — see your IP address.
For those unaware, your IP address stands for Internet Protocol, and it's what the internet or a local network uses to communicate with your device. It also contains information about your physical location, something that's frequently exploited in doxxing attempts where personal information is published online for all the world to see.
As of February 28, when Twitter announced the feature's new widespread availability, "Enable audio and video calling" is now turned on for all users by default, which lets users call each other in a similar vein to messaging apps like WhatsApp. Simply following a person on the platform is enough to open yourself up to video and audio calls from them.
In the menu to toggle this on and off (more on that in a bit), you'll see another switch that says "Enhanced call privacy." Its risk should be clear from the description: "Enable this setting to avoid revealing your IP address to your contact during your call." It's turned off by default, which means that your IP address is automatically shared with whoever you're calling.
If you'd rather not be bothered by junk calls or accidentally reveal personal information to the web, here are the settings you need to change now. Frustratingly, you won't be able to toggle these settings on desktop, as the option is only available on the platform's mobile version. So you can only change it on your phone for now at least.
