How to Password-Protect a Folder on iPhone (2026)

iOS has no native folder password protection.

iOS does not have a native feature for password-protecting folders. There is no setting, no toggle, and no built-in app that lets you put a password on a folder of files the way Samsung's Secure Folder works on Android or a zip password works on a computer.

That is not an oversight. Apple's security model relies on device-level encryption (the entire disk is encrypted when the phone is locked) and per-app authentication (Face ID, Touch ID, or passcode for specific apps). Folder-level protection sits between these two layers, and Apple has not filled that gap.

This guide covers five methods to approximate folder-level password protection on iPhone, ranked from quickest to most secure. Each method has different trade-offs, and the right choice depends on what you are protecting and from whom.

The Quick Answer

The closest native equivalent to a password-protected folder on iPhone is a locked note in the Notes app. Create a note, add files to it, and lock the note with a separate password or Face ID. It takes under a minute and requires no additional apps.

For genuine password-protected folders with encryption, you need a third-party app. Encrypted vault apps like Vaultaire create encrypted containers that function like folders, where every file is encrypted with AES-256-GCM and the key is derived from a pattern you draw.

Method 1: Lock Files in the Notes App

The Notes app is the fastest way to password-protect files on iPhone without installing anything.

Step-by-Step

1. Open the Notes app.
2. Create a new note (or open an existing one).
3. To add files: tap the camera icon to add photos/videos, or use the document scanner to scan pages. You can also paste text, links, and small attachments.
4. Tap the three-dot menu (top right) or the share button.
5. Tap Lock.
6. Choose to lock with Face ID or set a custom password.
7. Tap the lock icon in the toolbar (or leave the note -- it locks automatically after a period of inactivity).

What This Protects

• The note contents are hidden behind Face ID or a custom password.
• Individual locked notes can have different passwords (though iOS encourages using your device passcode as the default).
• Locked notes do not appear in previews, widgets, or Spotlight results.

Limitations

• File type restrictions. Notes supports photos, videos (with size limits), PDFs, and scanned documents. Large files and many file formats (zip archives, raw images, application files) cannot be embedded.
• Not a real folder. Each locked note is a single container. There is no folder hierarchy, no subfolder organization, no batch file management.
• iCloud sync. If Notes syncs to iCloud, locked note contents sync to Apple's servers. Apple holds the encryption keys for standard iCloud. The note's lock is access control on top of Apple-managed encryption, not independent user-controlled encryption.
• Share sheet does not import to locked notes. You cannot use the iOS share sheet to send a file directly into a locked note. You must open the note and add files manually.

Protection Level

Notes lock is access control. Someone who gains access to your iCloud account can theoretically access the locked note's data through Apple's systems. The lock prevents casual access on the device but does not provide independent encryption with a key only you hold.

Method 2: Use the Files App with iCloud Drive

The Files app provides basic folder organization, but iOS does not support password-protecting folders in Files. However, you can achieve partial protection through a combination of the Files app and iCloud Drive.

Step-by-Step

1. Open the Files app.
2. Navigate to iCloud Drive or On My iPhone.
3. Tap and hold in empty space, then tap New Folder.
4. Name the folder and add files to it.

The Problem

This creates a standard folder with no password, no lock, and no access restriction. Anyone who opens the Files app on your unlocked phone can see the folder and its contents.

Partial Workaround: Screen Time Restrictions

You can restrict access to the Files app using Screen Time:

1. Go to Settings > Screen Time > App Limits.
2. Add a limit for the Files app category.
3. Set the limit to 1 minute.
4. Require your Screen Time passcode to extend the limit.

After one minute of use, the Files app locks behind the Screen Time passcode. This is a blunt instrument -- it locks the entire app, not a specific folder -- but it adds a barrier.

Why this is weak: Screen Time passcodes are 4 digits. They can be reset by anyone who knows your Apple ID password. Screen Time was designed for parental controls, not security. A determined person can bypass it.

Method 3: Create a Password-Protected Zip or PDF

You can create password-protected archives on a Mac or PC and transfer them to your iPhone.

Step-by-Step (Using a Mac)

1. Place the files you want to protect into a folder on your Mac.
2. Open Terminal.
3. Run: zip -er protected.zip /path/to/folder/
4. Enter a password when prompted.
5. AirDrop or transfer the .zip file to your iPhone.
6. The file lives in the Files app. When you tap to open it, iOS asks for the password.

Step-by-Step (Using a PDF)

1. On your Mac, open the file in Preview.
2. Go to File > Export as PDF.
3. Check the Encrypt checkbox and set a password.
4. Transfer the password-protected PDF to your iPhone.

Limitations

• This works for individual files or small archives, not for an ongoing "folder" you add to regularly.
• Zip encryption (ZipCrypto) is weak by modern standards. The AES-256 zip option is stronger but requires specific tools.
• You cannot add files to a password-protected zip natively on iPhone.
• This is a static protection, not a working folder.

Method 4: Use the Shortcuts App to Build a Protected Folder Flow

The Shortcuts app can create automation that mimics folder protection.

Concept

Build a Shortcut that:

1. Prompts for a password (using "Ask for Input").
2. If the password matches, opens a specific folder in the Files app.
3. If the password does not match, shows an error.

Step-by-Step

1. Open the Shortcuts app.
2. Tap + to create a new Shortcut.
3. Add an Ask for Input action, set it to Text, with the prompt "Enter password."
4. Add an If action. Condition: "If [Provided Input] is [your password]."
5. In the If block, add an Open App action pointing to the Files app.
6. In the Otherwise block, add a Show Alert action with "Incorrect password."
7. Save the Shortcut and add it to your Home Screen.

Limitations

• Not real security. The password is stored in plain text inside the Shortcut. Anyone who opens the Shortcuts app can read it.
• The folder itself is unprotected. The Shortcut controls access to the Files app, but someone can open the Files app directly and navigate to the folder without using the Shortcut.
• No encryption. Files remain unencrypted on disk.

This method provides a friction layer, not a security layer. It stops someone from casually accessing files through your Home Screen shortcut. It does not stop someone who knows the Files app exists.

Method 5: Use an Encrypted Vault App

An encrypted vault app creates what iOS does not natively offer: a container where files are encrypted with a key only you control. This is the closest equivalent to a true password-protected folder.

How It Works

Encrypted vault apps like Vaultaire function as encrypted folders:

1. You create a vault (equivalent to a folder) by drawing a pattern on a 5x5 grid.
2. The pattern generates a 256-bit AES encryption key through PBKDF2 key derivation with 600,000 iterations.
3. Every file imported into the vault is encrypted with AES-256-GCM, the same standard used by the U.S. government for classified data (NIST SP 800-38D).
4. Metadata (file names, dates) is encrypted separately with ChaCha20.
5. When you close the app, the key is wiped from memory.

Step-by-Step (Using Vaultaire)

1. Download Vaultaire from the App Store.
2. Draw a pattern on the 5x5 grid to create your first vault.
3. Tap the import button to add files: photos, videos, documents, PDFs, or any file type.
4. Files are encrypted at the moment of import.
5. Delete the unencrypted originals from Photos or Files.
6. To access files, open the app and draw the same pattern.

Why This Is Different From Other Methods

The encrypted vault is the only method where no third party -- not Apple, not the app developer, not someone with your unlocked phone -- can access the contents without your key.

Additional Vault Features

Vaultaire adds capabilities beyond simple folder protection:

• Multiple vaults. Each pattern opens a different vault. There is no limit to the number of vaults (paid tier), and no registry reveals how many exist. Details.
• Plausible deniability. The existence of additional vaults cannot be proven. A forensic examiner sees encrypted data but cannot determine vault count or contents. Details.
• Duress mode. A designated pattern opens one vault and destroys the keys to all others. Details.
• Secure sharing. Share an encrypted vault with another person using a sharing phrase. Control expiration, access count, and export permissions. Details.
• Built-in camera. Photos and videos taken with the in-app camera are encrypted directly. No unencrypted copy touches the Photos library.

Which Method Should You Use?

The answer depends on your threat model:

Keeping files organized and out of casual view: Notes lock (Method 1) or Screen Time restriction (Method 2). Quick, free, no app install.

Protecting a few specific documents: Password-protected zip or PDF (Method 3). Works for static files you do not frequently update.

Protecting files from someone who shares your device or knows your passcode: Encrypted vault (Method 5). The only option where a separate key controls access, not the device passcode.

Protecting files from forensic analysis, legal requests, or cloud exposure: Encrypted vault with zero-knowledge architecture (Method 5). The only option where no one besides you can access the data.

Adding a quick friction layer to the Home Screen: Shortcuts automation (Method 4). Understand that this provides convenience, not security.

Frequently Asked Questions

Can you password-protect a folder on iPhone natively?

No. iOS does not support folder-level password protection. There is no built-in equivalent to Samsung's Secure Folder or Windows folder encryption. The closest native option is locking a note in the Notes app, which supports photos, videos, and documents but is not a true folder with file management capabilities.

Is there a "Secure Folder" for iPhone like Samsung?

Not a direct equivalent. Samsung's Secure Folder creates an isolated, encrypted partition on the device. The closest iPhone alternatives are: (1) the Notes app lock for small collections of files, (2) an encrypted vault app for genuine encryption with a key you control, or (3) the Hidden Album in Photos (for photos and videos only, no encryption).

Can I lock the Files app on iPhone?

Not directly. The Files app does not support Face ID or password protection. You can use Screen Time app limits to add a friction layer (the app locks behind a Screen Time passcode after a set time limit), but Screen Time was designed for parental controls, not security. The passcode is 4 digits and can be reset through Apple ID.

What is the difference between password protection and encryption?

Password protection (access control) puts a gate in front of data. The data behind the gate remains in its original, readable format. If someone finds another path to the data (through a backup, file system access, or by bypassing the gate), they can read it.

Encryption transforms the data itself. The original file is replaced by data that is mathematically indistinguishable from random noise. Without the decryption key, there is no path to the original content. The "gate" is not in front of the data -- it is the data.

Pattern-based encryption takes this further by deriving the key from something you physically draw, making the key both strong and memorable without storing it anywhere.

Will Apple add Secure Folder to iPhone?

Apple has not announced folder-level encryption for iOS. Apple's approach has been to strengthen device-level encryption (full-disk encryption with Secure Enclave) and offer Advanced Data Protection for iCloud. Whether Apple will add a Secure Folder equivalent is unknown. For now, third-party encrypted vault apps fill this gap.

The Bottom Line

iOS does not have password-protected folders. Apple chose a different security architecture: full-disk encryption when the device is locked, per-app authentication, and optional iCloud end-to-end encryption.

For most everyday file organization, the Notes lock is good enough. For files that need genuine protection -- from partners, forensics, cloud exposure, or anyone who is not you -- encryption is the answer. Not a password on a folder, but a mathematical transformation that makes the contents unreadable without a key that exists only in your head.

The question is not "how do I put a password on a folder?" The question is "who am I protecting this folder from?" The answer determines the method.
