If you are managing more than one Instagram account, you can manage up to 5 profiles from your one Instagram app on your mobile phone.
Following are the steps to set up additional accounts on your app.
Step 1: Go into your Instagram App.
Step 2: Click on your profile image in the bottom right hand corner.
Step 3: Once in your Profile, click on Settings.
(For some people this might be the cog sign under the Following numbers, for others it might be under the ellipses (…) in the top right hand corner. It depends on whether you have a personal or business account.
Step 4: Click on Add Account
Step 5: Log into the account you’re wanting to add to your app
Once you’re logged in, your account is added and you are ready to post.
To swap from one account to another
When you want to swap from one Instagram account to another, click on the profile image in the bottom right hand corner so you are taken to the current account’s profile page.
Then click on the profile name at the top of the page.
A drop down of the accounts set up in your Instagram app will appear. Click on the account you wish to use and you will be taken into its profile page.
NB: Once you have added more than one account, be sure to check which account is active before you post! It’s easy to accidentally post to the wrong account.
