Keeping Personal and Business Accounts Separate on Your Mac and iPhone

If you run a business, or work for one, there is a good chance your Mac and iPhone are used for both work and home. That is normal, and it works fine until the day it does not. A work email gets sent from a personal address. A business file ends up in your family photo storage. A staff member leaves with the only copy of something important. Or one stolen password opens up both your work and your private life.

A few simple habits keep the two apart. This guide covers the ones that make the most difference on a Mac and an iPhone.

Use your work account for work only

Start with email and Microsoft 365. Sign in to your business email and apps with your work account, and keep your personal Microsoft account for personal things. Do not sign up to shopping, streaming or social media sites with your work email address, because the business owns that email address, and the account is awkward to move or close when you leave.

If you use OneDrive on a Mac, you can add both a personal account and a work account to the same app. They stay separate, with their own storage, and you cannot sync or share folders between them, although you can copy or drag files across. You can only add one personal account.

Separate your browsing in Safari

If you use Safari 17 or later, profiles let you keep work and personal browsing apart. Each profile has its own history, cookies, website data, extensions, Tab Groups and favourites, so you can be signed in to a work account in one profile and a personal one in another without them getting mixed up.

To set one up, open Safari, choose Settings, click Profiles and follow the steps. Name one profile Work and keep the other as Personal. One thing profiles do not separate is your saved passwords, which are shared between profiles. It is still worth using different sign-ins for work and personal sites.

Use a separate user account on a shared Mac

If a Mac is shared with family or colleagues, or you want a firmer line between work and home, give each person or purpose their own user account. In System Settings, click Users & Groups and add a user. Each account has its own settings, and a standard user can change only their own.

Keep one administrator account, protect it with a strong password, and do not set it to log in automatically, because anyone who restarts the Mac could then gain administrator access.

Use Focus on your iPhone

On an iPhone, a Work Focus and a Personal Focus help keep the two apart. When you set up a Focus, you can add filters that choose which email account or which calendar the apps show. Once the filters are set, Work shows your work email and calendar and Personal shows your own.

A Focus hides the other account rather than separating it completely, so it helps with distraction and mix-ups more than it protects data.

Keep your Apple Account personal

Your Apple Account holds your photos, purchases, backups and the ability to find or lock your devices. Keep it personal and private to you, and do not use it to hold business data that the business would need if you left. If your business owns the devices, the right tool is a Managed Apple Account, which the business owns and manages, and which keeps business data apart from personal data. Our guide to Apple Business and Apple Accounts on company devices explains how that works.

Why it pays off when someone leaves

The real benefit of all this shows up when staff leave, change jobs or lose a phone. If work lives in work accounts, you can switch those accounts off, remove the work profile and move on, and the person keeps their own photos, messages and purchases. If everything is tangled together, one of you loses something.

It also limits the damage if a password is stolen. A criminal who gets into a work account does not automatically reach your personal accounts. A good password manager helps too, and our guide to the Apple Passwords app explains what it can and cannot do for a team.

Where to start

If you only do one thing, use your work account for work and nothing else. Then add a Safari profile, then a Work Focus on your iPhone. Use a separate Mac user account if the Mac is shared.
