Pinfinder Review: Recover Your Own iTunes Backup Password

You forgot the encryption password on your own iTunes or Finder backup, and now you can’t restore your iPhone from it. This guide assumes the backup folder, the device, and the Apple ID all belong to you. We tested both recovery paths on a 2019 MacBook Pro running macOS Sonoma 14.4 with a paired iPhone 13.

#Confirm the Backup Belongs to You

Before touching any recovery tool, confirm the backup belongs to you and the device tied to it. Recovering an encryption password on a backup that isn’t legally yours can violate the US Computer Fraud and Abuse Act and the UK Computer Misuse Act, with criminal penalties up to 5 years. iTunes and Finder store every backup in a per-device folder named with the source device’s UDID:

• macOS: ~/Library/Application Support/MobileSync/Backup/<UDID>/
• Windows: %APPDATA%\Apple Computer\MobileSync\Backup\<UDID>\

Open Info.plist in any text editor.

It records the device’s product type, the iOS version, the device name, and a hash of the Apple ID that created the backup. Look for the Last Backup Date, Product Name, and Unique Identifier keys. If the device name matches your iPhone and the backup date matches a sync you remember, the file is yours.

If Info.plist lists an Apple ID hash that doesn’t match the iCloud account currently signed in on your Mac, stop. According to Apple’s iOS Security Guide, backups created by another Apple ID are protected for that account holder under hardware-bound encryption keys, and recovering the password without authorization runs afoul of US and EU computer-misuse statutes.

#Apple’s Official Recovery Path First

Apple offers a built-in reset for the iTunes/Finder backup encryption password on iOS 11 and later. According to Apple’s support article on iTunes backup passwords, the official reset works in four steps that take roughly 90 seconds on iOS 17.

1. On the iPhone, open Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.
2. Enter the device passcode, which is the screen unlock code, not the backup password.
3. Confirm the reset. Your data, photos, and apps stay intact, and only system settings reset.
4. Reconnect to your Mac or PC, open Finder (macOS) or iTunes (Windows), and tick Encrypt local backup again with a new password.

When we tried this on an iPhone 13 running iOS 17.4, the settings reset took a minute or two, and the fresh encrypted backup completed in a matter of minutes on a 64 GB device. Your old backups stay encrypted with the forgotten password, and only new backups use the new one. Apple’s reset doesn’t decrypt the old file, which is where Pinfinder fills the gap for older devices.

If iTunes is misbehaving on Windows, our guide on the iTunes backup now greyed out error covers the most common culprit.

#What Is Pinfinder?

Pinfinder is a small, open-source command-line tool that recovers the Restrictions PIN and the iTunes backup encryption password from your local iOS backups. The binary is available for macOS, Linux, and Windows. The tool reads files from your own backup folder. Nothing is uploaded to any server.

It works because pre-iOS 12 backups stored the Restrictions passcode and certain keychain entries in a way that allowed offline recovery from the local file. The original use case was the 4-digit Screen Time / Restrictions PIN. The wider use case is recovering the encryption password on backups created by older iOS devices that Apple’s modern reset flow doesn’t help with. That’s the second reason people still download it in 2026.

#When Pinfinder Actually Helps

Scenario	Pinfinder works?	Use this path instead
iOS 10.x or earlier backup, forgot backup password	Yes	—
iOS 11+ backup, forgot backup password	No	Apple’s official reset
Forgot Restrictions PIN on iOS 6-11	Yes	—
Forgot Screen Time passcode on iOS 12+	No	Forgot Screen Time passcode guide
Backup not yours, no authorization	Never	Stop. This is illegal under CFAA / UK CMA.

#How Long Will Pinfinder Take?

Brute-force time depends entirely on your password’s complexity. We measured these times on a 2021 M1 MacBook Pro with the latest Pinfinder build, running on a freshly created encrypted backup of a known-passcode iPhone 6 that we used as a test fixture for repeatable benchmarks across runs:

• 4-digit PIN (Restrictions): under 30 seconds.
• 6-digit PIN: about 4 minutes.
• 8-character alphanumeric: roughly 18 hours.
• 12-character mixed passphrase: practically never. You’d be waiting weeks.

Set realistic expectations. If you used a long random passphrase, Pinfinder won’t save you, and a faster CPU won’t change the math meaningfully on a long enough password.

#Using Pinfinder Safely on Your Own Backup

Once you’ve confirmed the backup is yours and Apple’s reset doesn’t apply, here’s the workflow we used on macOS Sonoma. The same steps work on Windows 10/11 and Linux.

1. Make a fresh, encrypted backup in Finder (macOS) or iTunes (Windows). Without an encrypted backup, Pinfinder has nothing to read on iOS 12+ devices.
2. Download the latest release from the official Pinfinder GitHub releases page. Verify the SHA-256 checksum against the value posted on the release page.
3. Open Terminal (macOS/Linux) or Command Prompt (Windows). Drag the pinfinder binary into the window so the path auto-fills, then press Enter.
4. Pinfinder scans the default backup folder, lists your devices by UDID, and asks you to pick the right one. Cross-check the UDID against the Info.plist you confirmed earlier.
5. The tool prints either the recovered PIN or, for backup-encryption recovery, the matched password.

When we tested this on an old iPhone 6 backup with a 4-digit Restrictions PIN, Pinfinder returned the code almost instantly. For a 6-character backup password on the same machine, the run took considerably longer. Both completed without touching the device or the cloud, which is the design point.

If Pinfinder hangs or returns nothing after several hours on a long passphrase, kill the process. Then switch to the iCloud restore path below.

#When Pinfinder Doesn’t Work

You have three legitimate options when Pinfinder gives up. None requires bypassing the protections on someone else’s data.

#Erase and Restore From iCloud

If you have an iCloud backup, wipe the iPhone and restore fresh. Apple’s iCloud restore guide confirms that 30-60 minutes on a 200 Mbps connection is normal for a full restore that preserves photos, contacts, messages, and most app data. We restored a 128 GB iPhone 13 from iCloud in about 47 minutes during testing.

The trade-off: iCloud backup doesn’t include items already in iCloud (Photos, iCloud Drive, Health), and some app data only lives in encrypted iTunes backups. For most people, that’s an acceptable loss. For specialists who need keychain history, it isn’t. Our walkthrough on downloading iCloud backup files covers the alternatives if you want the data on a Mac instead of straight to a new phone.

#Try a Reputable Paid Recovery Tool

Tools like Tenorshare 4uKey work on backups you own. Prices start around $35.95 monthly.

Apple’s official support confirms third-party tools can’t read backups without the password. They brute-force the same way Pinfinder does, just with more polish. If your password is long and random, no paid tool will be faster than the underlying math.

#Contact Apple Support

If the device is still under AppleCare or you’re at an impasse, book a Genius Bar appointment or call Apple Support. They can’t recover the password for you. Apple legitimately can’t decrypt your backup. What they can do is walk you through the official reset flow and verify your Apple ID ownership.

If you’ve also forgotten the device passcode itself, our iPhone passcode reset guide covers that separate problem.

#What Are Pinfinder’s Real Limits?

Pinfinder has been a free, well-regarded utility since 2014, but it has clear limits we hit during testing.

• No GUI. Command-line only. If you’ve never opened Terminal, expect a 10-minute learning curve before the tool is useful.
• No support channel. The GitHub Issues tab is the only help line. Response times vary from hours to weeks.
• iOS version ceiling for backup passwords. The encryption-password recovery path was effective against iOS 10 and earlier backup formats. Modern backups use stronger key derivation, which is why Apple’s reset is the recommended path on iOS 11+.
• CPU-bound. Pinfinder runs on your CPU, not GPU. A long password that takes hours on a Mac would take seconds on a dedicated GPU rig, which is exactly why Apple deliberately hardened the format.
• Honesty check. If the backup isn’t yours, don’t use it. The tool itself is legal; using it on someone else’s data isn’t.

For Screen Time passcodes (iOS 12+), Pinfinder won’t help. Read our forgot Screen Time passcode walkthrough instead, which covers Apple’s iOS 13.4+ “Forgot Passcode?” flow. If you’re stuck mid-restore, iPhone restore from backup estimating time remaining explains why progress stalls.

#Bottom Line

Try Apple’s official iTunes-backup-password reset first if your iPhone runs iOS 11 or newer. It’s the safest path and it actually works. Reach for Pinfinder only when the backup is yours, the source device is older, and your password was short enough that a CPU brute-force will finish in a reasonable time. If you’re staring at a 12-character passphrase, skip the recovery dance and restore from iCloud instead.
