To encrypt iPhone backup files, connect your iPhone to a Mac or Windows PC, choose a local backup, turn on Encrypt local backup, set a password, then run the backup. That is the simple part. The important part is keeping that password safe, because Apple cannot unlock an old encrypted iPhone backup if you forget it.

Use Finder on modern Macs. Use Apple Devices on modern Windows PCs. Use iTunes only if your older setup still depends on it. If you are on Windows and want easier local backup browsing or selected file export later, AltTunes can help after you keep the encrypted-backup password.

Quick Answer: How to Encrypt iPhone Backup

To encrypt iPhone backup data locally, use the backup app for your computer, select your iPhone, choose the computer/local backup option, enable Encrypt local backup, create a password, and start the backup. Apple documents this for Finder, Apple Devices, and iTunes in its encrypted backup guide.

Quick Takeaways Before You Start

• Encrypted local backups protect the iPhone backup on your computer with a password you set.
• Apple says encrypted backups can include saved passwords, Wi-Fi settings, website history, Health data, and call history.
• Encrypted backups do not include Face ID, Touch ID, or the device passcode.
• iCloud backup and encrypted local computer backup are different backup paths.
• Apple Devices is the modern Windows path; iTunes is now the older fallback.
• AltTunes is useful for Windows backup management and selected export, not forgotten password recovery.

Before we begin

Pick the tool by computer first. On Mac, Finder is the clean Apple path. On Windows, Apple Devices is the current Apple path and iTunes is the old one. Both can create an encrypted local backup when you turn on the encryption checkbox.

Windows users have another practical option after the backup exists. AltTunes is Softorino's iPhone file manager for Windows. It helps you back up an iPhone over USB, browse local backup data, and export selected files to your PC instead of restoring the whole phone.

AltTunes does not bypass Apple's backup encryption. If the backup is encrypted, you still need the password. That limitation is a good thing. A tool that claims to crack your backup password is probably selling you a headache.

What Does an Encrypted iPhone Backup Mean?

An encrypted iPhone backup is a local computer backup protected by a password. The backup file sits on your Mac or Windows PC, and the password controls restore access to protected data inside it.

Apple says encrypted backups can include data that regular local backups may leave out: saved passwords, Wi-Fi settings, website history, Health data, and call history. That makes encryption useful when you want a fuller restore after replacing, resetting, or losing an iPhone.

Encrypted local backup is not the same as iCloud backup. iCloud backup lives in Apple's cloud and uses your Apple Account. Local encrypted backup lives on your computer and uses the password you create during setup. iCloud Advanced Data Protection is separate again, because it changes protection for iCloud data, not the local backup file on your PC or Mac.

Should You Encrypt iPhone Backup Files?

You should encrypt iPhone backup files if you want the most complete local restore and you can store the password safely. For most people, that is the right tradeoff. The backup includes more sensitive data, and the password keeps the local copy protected if someone gets access to your computer.

You should think twice only if password custody is a bigger risk than backup completeness. If you know you will lose the password, an encrypted backup can become useless when you need it most. Use a password manager or a sealed recovery note before you click Back Up Now.

The practical rule is simple: encrypt the backup, save the password, and verify the lock icon after the backup finishes. Do not rely on memory. Future you will not remember which clever password you invented at 1:00 a.m.

How to Encrypt iPhone Backup on Mac with Finder

Use Finder to encrypt iPhone backup files on any Mac running macOS Catalina or newer. Apple moved iPhone management out of iTunes, so Finder is now the normal Mac route.

1. Connect your iPhone to your Mac with a USB cable.
2. Unlock your iPhone and tap Trust This Computer if iOS asks.
3. Open Finder.
4. Select your iPhone in the Finder sidebar.
5. Open the General tab.
6. Under Backups, choose Back up all of the data on your iPhone to this Mac.
7. Check Encrypt local backup.
8. Enter a strong password and save it in your password manager.
9. Click Set Password.
10. Click Back Up Now.

After the backup finishes, open Manage Backups and check for the lock icon. The lock is your quick visual proof that Finder created an encrypted local backup.

How to Encrypt iPhone Backup on Windows in 2026

Windows users now have 2 Apple paths to encrypt iPhone backup data: Apple Devices and iTunes. Use Apple Devices first if it is available on your PC. Use iTunes only if you are on an older setup or Apple Devices does not fit your workflow.

Option 1. Use Apple Devices on Windows

Apple Devices gives Windows users Apple's modern iPhone management app without dragging the whole old iTunes experience back onto the PC. Apple also documents Windows backup steps in its Windows backup guide.

1. Install or open Apple Devices from Microsoft Store.
2. Connect your iPhone with a USB cable.
3. Unlock the iPhone and trust the computer.
4. Select your iPhone in Apple Devices.
5. Open the backup section.
6. Choose the local backup option for this computer.
7. Turn on Encrypt local backup.
8. Create and confirm the password.
9. Start the backup.

Option 2. Use iTunes on Older Windows Setups

iTunes still works for encrypted backups, but Windows users have better options now. Keep iTunes only if your PC still depends on it or Apple Devices is not available.

1. Open iTunes.
2. Connect your iPhone with a USB cable.
3. Click the iPhone icon when it appears.
4. Open the Summary page.
5. Under Backups, check Encrypt local backup or Encrypt iPhone backup.
6. Enter a password you can keep.
7. Click Back Up Now.

If you only need Apple-native backup creation, stop here. If you also want to browse local backup data or export selected iPhone files on Windows, use the AltTunes section below.

How to Verify Your iPhone Backup Is Encrypted

Do not assume the backup is encrypted because the checkbox was on. Check the backup list after the job finishes.

On Mac, open Finder, select your iPhone, and go to Manage Backups. On Windows, use Apple Devices or iTunes and open the backup management area. Apple marks encrypted backups with a lock icon next to the device name and backup date.

If you see the lock, the backup is encrypted. If you do not see it, create a new encrypted iPhone backup before you rely on it. This small check prevents the ugly surprise where you reset a phone and discover the backup did not include the sensitive data you expected.

How AltTunes Helps Windows Users Manage iPhone Backups

AltTunes is an iPhone file manager for Windows. It helps Windows users back up an iPhone over USB, browse local backup data, and export photos, music, messages, contacts, videos, and files to a PC.

AltTunes fits this article because encryption creates the safer backup, but Windows users often need more control after that. Maybe you need 20 message attachments, not a full restore. Maybe you want photos copied to a project folder. Maybe you want backup files on local storage instead of a cloud-only path.

Here is the safe way to frame it: AltTunes can help you manage and export backup data when access is allowed. AltTunes cannot recover, crack, or bypass a forgotten encrypted backup password. You need the password for encrypted backup access.

1. Back up your iPhone to your PC over USB.
2. Browse local backup data when you have access.
3. Export selected photos, music, messages, contacts, videos, and files.
4. Convert HEIC photos to JPG during export where the app supports it.
5. Move iPhone data without using iTunes for every small task.

How to Back Up Your iPhone with AltTunes

AltTunes works on Windows 10 and 11. Install it on your PC, connect your iPhone, and keep the phone unlocked while the app reads the device.

Step 1. Install AltTunes on Your PC

Download AltTunes, install it, and connect your iPhone with a USB cable. Tap Trust This Computer on your iPhone if iOS asks.

AltTunes will show your iPhone in the app. From there, you can manage backups and export device data without digging through iTunes menus.

Step 2. Open the Apps or Backup Area

Choose the relevant device area in the AltTunes sidebar. Use the backup section for local backups, or use the export sections when you need specific iPhone data copied to your PC.

Step 3. Choose a Safe Password

Pick a password you can keep. Use a password manager if you have one. If a backup is encrypted and you lose the password, you lose access to that encrypted backup.

Choose the backup location on your PC, then start the backup. Keep the iPhone connected until AltTunes reports the backup is done.

What Encrypted iPhone Backups Include and Exclude

Encrypted backups are worth using because they can restore sensitive data that standard local backups may skip. Apple lists these examples for encrypted local backups:

• Saved passwords.
• Wi-Fi settings.
• Website history.
• Health data.
• Call history.

They do not include everything. Apple says local backups do not include Face ID, Touch ID, or the device passcode. Some cloud-synced data may also live in iCloud rather than inside the local backup.

If your goal is a safer full-device restore, encrypted local backup is the right choice. If your goal is cloud protection, check iCloud settings and Advanced Data Protection separately.

How to Extract Files from an Encrypted iPhone Backup with AltTunes

If you know the encrypted backup password, AltTunes can help you browse and export selected backup data on Windows. This is useful when you need one group of files instead of a full iPhone restore.

Step 1. Connect Your iPhone to Your PC

Connect the iPhone with USB and tap Trust This Computer. AltTunes will detect the device and show the available management options.

Step 2. Select the Backup and Enter the Password

Open the backup you want to browse. If the backup is encrypted, enter its password when AltTunes asks. No password means no access to that encrypted backup.

Step 3. Choose Files and Export Them

Select the files or folders you need, choose a destination on your PC, and export them. This is cleaner than restoring an entire iPhone just to recover a few items.

If you want a deeper walkthrough of the browsing side, read Softorino's guide to view iPhone backup files. If you are planning broader backup storage, use the guide to back up iPhone without iCloud.

What to Do If You Forgot Your iPhone Backup Password

If you forgot the password for an old encrypted backup, you cannot restore that backup. Apple cannot recover it for you, and AltTunes cannot bypass it.

You still have a few safe options:

1. Try passwords you may have used when you created the backup.
2. Check your password manager.
3. Check Mac Keychain if you saved the password there.
4. Use an iCloud backup if you have one.
5. Reset the encrypted backup password so future backups can use a new password.

Resetting the password does not unlock old encrypted backups. It only lets you create new encrypted backups with a new password. Apple's encrypted backup guide explains this reset behavior, so treat any password-recovery promise with suspicion.

How to Turn Off iPhone Backup Encryption

If you know the password, turn backup encryption off from the same app you used to make the backup. The setting lives near the local backup controls.

On Mac:

1. Connect your iPhone.
2. Open Finder and select the iPhone.
3. Uncheck Encrypt local backup.
4. Enter the backup password.

On Windows:

1. Open Apple Devices or iTunes.
2. Select your iPhone.
3. Uncheck Encrypt local backup or Encrypt iPhone backup.
4. Enter the password.

If you forgot the password, reset it on the iPhone instead. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. Apple says this resets settings such as your Home Screen layout, Wi-Fi passwords, and Apple Pay cards. It does not delete your photos, apps, or other personal data.

After that reset, connect the iPhone again and create a new encrypted backup password. Your old encrypted backups still need the old password.

Local Encrypted Backup vs iCloud Backup vs Advanced Data Protection

People mix these up because Apple uses encryption language in several places. Keep the backup paths separate.

Use encrypted local backup when you want a local restore file you control. Use iCloud backup when you want automatic cloud backup. Use AltTunes when the Windows problem is not encryption itself, but managing iPhone data without iTunes.

Extra iPhone Security Tips Before You Back Up

Backup encryption protects the backup file. It does not replace normal iPhone security.

Use these basics too:

1. Use a strong alphanumeric iPhone passcode.
2. Turn on two-factor authentication for your Apple Account.
3. Keep iOS updated.
4. Avoid sensitive work on public Wi-Fi unless you trust your VPN.
5. Turn on Erase Data if you want the iPhone to wipe after 10 failed passcode attempts.

You do not need to make this complicated. Use a strong passcode, encrypt local backups, save the backup password, and keep at least one recent backup you can trust.

Should You Use Finder, Apple Devices, iTunes, or AltTunes?

Use Finder if you are on Mac. Use Apple Devices if you are on a modern Windows PC and want Apple's native backup path. Use iTunes only if your setup still depends on it.

Use AltTunes if you are on Windows and want easier backup management, selective export, and a cleaner way to move iPhone data to your PC. It is not a magic password recovery tool. It is a practical Windows iPhone manager.

If AltTunes fits your setup, try the AltTunes iPhone backup tool and keep your local iPhone data easier to manage. If you use several Softorino apps, the Universal License gives you the core tools under one subscription.

FAQ

Final Take

Encrypt iPhone backup files if you care about a safer, more complete local restore. The setup takes a few minutes. The password decision deserves more attention than the checkbox.

On Mac, use Finder. On Windows, use Apple Devices or iTunes for Apple's native path. If you want cleaner Windows backup management and selected export, try AltTunes. It will not rescue a forgotten password, but it can make the rest of iPhone backup work less painful.
