Since February 2016, Instagram allows you to manage multiple accounts at once through their app. You can add up to 5 accounts on Instagram and quickly switch between them without the need to logout and login again. If you want to switch between added accounts, follow these steps:
- Go to your profile.
- Tap your username at the top of the screen.
- Tap the account you want to switch to.
- Post anything you want or interact with other profiles with this opened account.
Of course there are also apps that let you manage all of your accounts – like CoSchedule. And all the insights you need from your accounts you can find with a social media analytics tool, like Sotrender.
