How to create multiple Instagram accounts

Instagram encourages you to sign in using an email address, phone number, and Facebook profile. If you don't connect your Facebook to a single Instagram account, that's three separate ways. You can also add more using different email addresses, so if you have one for work and one for your private life, you could use both of these.
Instagram only lets you add five accounts to one device. In theory, you can create more by changing names between profiles; however, you won't be able to easily switch profiles through the single app. Don't forget that you can sign in through a web browser too.
