Instagram has began testing multiple account support through its app for Android users, but so far it's not available on iOS, Android Police reports. If you're on Android, you should be able to update your app and see the option to add more accounts right now.
So let's all do a shot for our friends who are social media managers (and these days it feels like there is a whole lot of them), because you know those guys are celebrating tonight.
Also, now that this exists, don't do that thing where you post something wild/pornographic/drunk from your work account when you meant to post it from your down-low personal account and get yourself fired. It's not a good look.
