You can add a second iCloud account on one iPhone, but it comes with trade-offs

Your iPhone can hold two iCloud accounts at the same time, but not in the way you might expect. You cannot straightforward log into a second iCloud account the way you would on a Mac. Instead, you set up a second user account on the device itself — called a secondary user — which lets a different person use the phone with their own iCloud data, apps, and settings. If you want to access a second iCloud account that belongs to you, the process is different and more limited.

The route you take depends on what you actually need: whether you want a family member to have their own space on your phone, or whether you need to check email or files from a second account that is yours.

Key Takeaways

  • iOS lets you create a secondary user account on one iPhone, which gives another person their own iCloud login, apps, and data without touching your account.
  • A secondary user account requires iOS 16.1 or later and works only on iPhone 13 and newer models.
  • If the second account is yours, you cannot fully log in through Settings — instead, you can access iCloud Mail, Photos, and Notes through the Mail and Notes apps by adding the account there.
  • Secondary user accounts do not share apps, photos, or settings with the main account, so each person gets a separate experience.
  • Switching between accounts on the lock screen takes a few seconds and does not require a password if Face ID or Touch ID is set up for both users.

Setting up a secondary user account for another person

If someone else needs to use your iPhone with their own iCloud account, create a secondary user. Open Settings, go to General, then tap Users & Accounts. Tap Add User and follow the prompts. The new user will need their own iCloud account — if they do not have one, they can create it during this setup, or you can create one for them beforehand at iCloud.com.

Once the secondary user is set up, they can unlock the phone using their own Face ID or Touch ID. Their apps, photos, messages, and iCloud data stay completely separate from yours. When they hand the phone back to you, swipe up from the lock screen and tap your name to switch back to your account.

Secondary user accounts work only on iPhone 13, iPhone 14, iPhone 15, and iPhone 16 models running iOS 16.1 or later. If you have an older iPhone, this option is not available.

Adding a second iCloud account that belongs to you

If the second account is yours and you want to check email or access files from it, you cannot log into it through Settings the way you would on a computer. Instead, add it to specific apps. Open the Mail app, tap Accounts at the bottom, then Add Account. Choose iCloud, enter the email address and password for your second account, and follow the prompts. You can now read and send email from that account without switching users.

You can do the same thing in the Notes app by going to Settings > Notes > Accounts and adding your second iCloud account there. This lets you see notes stored in that account's iCloud folder. For Photos, open the app, tap You at the bottom right, then Settings > iCloud Photos — but note that only one iCloud account can have iCloud Photos turned on at a time, so switching between accounts for photos means turning the feature off and on.

This method does not give you access to everything in the second account — you cannot see the second account's calendar, reminders, or contacts through the main Settings. If you need full access to a second account, using a secondary user account is the better choice.

Understanding what each method does and does not do

A secondary user account is the most complete option because it creates a separate login space. Each user gets their own home screen, their own installed apps, their own messages, and their own iCloud data. When one user is logged in, the other cannot see their photos, messages, or settings. This is useful for families or when you want to let someone borrow your phone without them seeing your private information.

Adding a second account to individual apps is less complete but faster if you only need email or notes. You stay logged into your main account on the home screen, but you can check the second account's email or notes without switching users. This method does not separate data — both accounts can see the same photos and messages on the device, which matters if privacy between the two accounts is important.

What happens to storage and backups

Each secondary user account has its own iCloud backup, separate from yours. When a secondary user sets up their account, their iPhone backup goes to their own iCloud storage, not to yours. This means you are not using your iCloud storage for their data, and they are not using theirs for yours.

If you add a second account only to the Mail app, that account's emails are stored on Apple's servers, not taking up space on your phone's storage. However, if you turn on iCloud Photos for that account, those photos will count against that account's iCloud storage limit, not yours.

Switching between accounts and managing access

On the lock screen, swipe up to see all users on the device. Tap the name of the person whose account you want to use. If Face ID or Touch ID is set up for that person, the phone unlocks when ready. If not, they will need to enter their passcode. Switching takes a few seconds and does not require you to sign out of your account — both accounts remain logged in.

If you want to prevent someone from accessing your account, go to Settings > General > Users & Accounts and tap Edit next to the secondary user you want to remove. Tap Delete User. Their account will be removed from the device, though their iCloud data remains safe on Apple's servers and they can log in from another device.

Common reasons this setup fails and how to fix them

If you cannot find Users & Accounts in Settings, your iPhone is too old or running an older version of iOS. Check Settings > General > About to see your iOS version. You need iOS 16.1 or later, and the feature works only on iPhone 13 and newer. If your phone is older, a secondary user account is not an option.

If a secondary user cannot sign in with their iCloud account, make sure they have an active iCloud account and that they are using the correct password. If they have two-factor authentication turned on for their Apple ID, they will need to complete that step during setup. If they forgot their password, they can reset it at iforgot.apple.com before trying again.

If you added a second account to Mail but emails are not showing up, check that you entered the correct password and that two-factor authentication is complete. Some older iCloud accounts may need an app-specific password instead of the regular iCloud password — Apple will prompt you if this is the case.

Frequently Asked Questions

Can I have two iCloud accounts on one iPhone without creating a secondary user?

Partially. You can add a second iCloud account to Mail, Notes, and a few other apps, but you cannot fully log into a second account through Settings. A secondary user account is the only way to have two complete, separate iCloud experiences on one phone.

Will adding a second account slow down my iPhone?

A secondary user account uses more storage because each user has their own apps and data. If your phone is already low on storage, adding a secondary user might make it slower. Check Settings > General > iPhone Storage to see how much space you have left before setting up a new user.

Can I use a secondary user account on an iPhone 12 or older?

No. Secondary user accounts require iOS 16.1 or later and work only on iPhone 13 and newer models. If you have an older iPhone, you can add a second account to individual apps like Mail, but you cannot create a separate user account.

What happens to a secondary user's data if I delete their account?

Their data is removed from your iPhone, but it stays safe in their iCloud account. They can sign into another device and access everything that was backed up. Deleting a secondary user from your phone does not delete their iCloud account or their backups.

Can both accounts use iCloud Photos at the same time?

No. Only one iCloud account can have iCloud Photos turned on per device. If you need both accounts to sync photos, you will need to turn the feature off for one account and on for the other, or use a secondary user account so each person has their own separate photo library.
