How many Instagram accounts can you have on one iPhone?

The app lets you add several accounts and switch between them, but for an agency the real question is different: how many you can have without Instagram linking them. The answer depends on how many identities the phone has, not on how many accounts fit in the app.

What the app allows

Within the app you can add several accounts and switch between them without logging out. It is handy for someone with a personal and a business account, but they all share the same phone.

Why accounts get linked

Accounts that live on the same phone share many signals: the device identifier, data stored by apps, the network and the location. From these, a platform can infer that the same person runs them.

If accounts are linked, a restriction on one can affect the others. That is why agencies keep each account on its own phone or its own identity.

One identity per account

The rule of thumb is one account per identity: its own phone, data, network and location. Doing it with physical phones is expensive and bulky; doing it with emulators is cheap, but they are not real iPhones.

How many accounts per physical phone

• Several accounts in the same app: as many as you like, but they all share one identity.
• One phone per account: separate, but you need as many phones as accounts.
• Isolated iPhones inside one physical phone: one identity per account, without multiplying the hardware.
