Fact: 94 percent of all college graduates end up becoming social media managers . Instagram knows this and is now testing support for multiple accounts, according to both Android Police and Droid Life. The option seems to be available to only select users on version 7.12.0, which itself is only available for Android beta testers, and can be found by scrolling all the way to the bottom of settings.
Right now, the only way to switch between your personal account, your small business' account, and your novelty account of cheap food mocked up to look like fancy food, is to log out of Instagram entirely before inputting new credentials. Of course, a feature appearing in beta is no guarantee that it'll make it to the public-facing app, but with Instagram recently cracking down on third-party apps, the feature seems both inevitable and necessary.
