I was curious if there was a way to make another Instagram account on the same device, with the same phone number and email, but keep it hidden from my followers?
Hello, whilst technically you can have multiple Instagram accounts with the same email address, there is a strong likelihood that you will find yourself out of the second account if ever you forget your password.
Instagram doesn't endorse this, and a simple solution of having two different Instagram accounts on your phone would be just by a Gmail account, and using this to create a secondary account, whilst using the same number.
