How to Lock Apps and Photos with Face ID: Complete 2026 Guide
Your iPhone holds your entire digital life — banking apps, private messages, intimate photos, work documents, and more. When you hand your phone to a friend to show them a vacation picture or pass it to a child to watch a video, there's a real risk they'll swipe into something you'd rather keep private. Fortunately, Apple has expanded its privacy toolkit dramatically, and you can now lock apps and photos with Face ID directly from iOS — no jailbreak, no shady downloads required.
This guide walks you through every official method available in 2026, plus advanced tips for protecting sensitive content across your entire device.
What Does It Mean to Lock Apps and Photos with Face ID?
Locking apps and photos with Face ID means requiring biometric authentication — a successful face scan — before an app opens or specific media becomes visible. Even if someone unlocks your iPhone with the passcode or has it open in their hand, they cannot access locked items without your face.
This feature became native to iOS 18 and was refined further in iOS 18.2 and later updates, giving users granular control over what stays private. It works on any iPhone with Face ID hardware (iPhone X and newer) and any iPad Pro with TrueDepth cameras. Touch ID devices use the same menus but authenticate with a fingerprint instead.
Why This Matters for Your Privacy
Studies consistently show that the people most likely to snoop through your phone are people you know — partners, friends, coworkers, and family members. A device passcode alone doesn't help when those people are already trusted with that code. App-level and photo-level locking adds a second perimeter that even authorized users can't cross.
How to Lock Any App with Face ID on iPhone (iOS 18+)
Starting in iOS 18, Apple introduced a system-wide feature called "Require Face ID" that lets you lock virtually any app on your iPhone. Here's the step-by-step process:
- Unlock your iPhone and go to the Home Screen.
- Find the app you want to lock (for example, Notes, Messages, WhatsApp, or your banking app).
- Touch and hold the app icon until the context menu appears.
- Tap Require Face ID (on Touch ID models it will say "Require Touch ID").
- Confirm by tapping Require Face ID again in the pop-up.
- Authenticate with Face ID to finalize the change.
From now on, every time you or anyone else taps that app, Face ID must succeed before the contents become visible. The app will also be hidden from Spotlight search results, Siri suggestions, and notifications previews when the screen is locked.
How to Unlock or Remove the Face ID Requirement
If you change your mind, the process reverses easily:
- Long-press the locked app icon.
- Tap Don't Require Face ID.
- Authenticate with Face ID one final time to confirm.
How to Hide Apps Completely with Face ID
Beyond simply locking apps, iOS 18 introduced a true "Hide" function that moves apps to a locked Hidden folder inside your App Library. Hidden apps don't appear on your Home Screen, don't show up in search, don't generate notifications, and are invisible to anyone scrolling through your phone.
- Long-press the app icon you want to hide.
- Tap Require Face ID.
- Select Hide and Require Face ID from the menu.
- Confirm and authenticate.
To find hidden apps later, swipe past your last Home Screen page to enter the App Library, scroll to the bottom, and tap the Hidden folder. Face ID will be required to open it.
How to Lock Photos with Face ID
Photos deserve special attention because they often contain the most personal content on your device. Apple offers two layers of photo protection — the Hidden album and the Recently Deleted album — both locked behind Face ID by default in modern iOS versions.
Step 1: Move Photos to the Hidden Album
- Open the Photos app.
- Find the photo or video you want to lock.
- Tap the three-dot menu (More button) in the top right.
- Select Hide.
- Confirm by tapping Hide Photo.
The image disappears from your main library, Memories, Featured Photos, and shared albums. It moves to a separate Hidden album that requires Face ID to view.
Step 2: Verify Face ID Is Enabled for the Hidden Album
This setting is on by default but always worth confirming:
- Open Settings.
- Scroll down and tap Apps, then Photos.
- Make sure Use Face ID is toggled on.
- Confirm Show Hidden Album is enabled if you want the album visible in the Utilities section. Turning it off hides the album entirely.
Step 3: Access Hidden Photos Securely
- Open the Photos app.
- Tap the Collections tab or scroll to the bottom of the main view.
- Look under Utilities and tap Hidden.
- Authenticate with Face ID to view the locked content.
Comparison: Native iOS Methods for Locking Content
Not every method gives you the same level of protection. Here's how the available options stack up:
| Method | Hides from Home Screen | Hides Notifications | Requires Face ID | Best For |
|---|---|---|---|---|
| Require Face ID | No | Partial | Yes | Daily-use apps you want extra-secure |
| Hide and Require Face ID | Yes | Yes | Yes | Apps you rarely use or want invisible |
| Photos Hidden Album | N/A | N/A | Yes | Sensitive images and videos |
| Screen Time App Limits | No | No | Passcode-based | Parental controls, time limits |
| Guided Access | N/A | N/A | Yes (Face ID exit) | Handing phone to someone temporarily |
How to Lock Apps with Face ID Using Screen Time
Before iOS 18, the most common workaround for locking apps was Screen Time, and it still works well today — especially if you want time-based limits rather than pure biometric locks.
- Open Settings and tap Screen Time.
- Tap App Limits, then Add Limit.
- Authenticate with Face ID or enter your Screen Time passcode.
- Select the app categories or individual apps to limit.
- Set the time to 1 minute (the lowest possible).
- Make sure Block at End of Limit is enabled.
After one minute of use per day, the app becomes inaccessible without your Screen Time passcode. While not as elegant as native Face ID locking, this approach is excellent for parental controls and for apps that don't yet support the Require Face ID option.
How to Lock Notes with Face ID
The Notes app has supported per-note locking for years, and the system was upgraded in 2023 to allow Face ID directly without needing a separate password.
- Open Settings → Notes → Password.
- Choose Use Device Passcode for the easiest setup (this enables Face ID automatically).
- Return to the Notes app, open the note you want to protect.
- Tap the three-dot menu and select Lock.
- Tap the lock icon at the top of the note to seal it.
How to Lock Specific Messages and WhatsApp Chats
Both Apple Messages and WhatsApp now offer chat-level locking. In WhatsApp, swipe left on any chat, tap the lock icon, and confirm. Locked chats appear in a separate folder accessible only with Face ID. For maximum coverage, apply the system-wide "Require Face ID" to the entire WhatsApp app as well.
Tips for Stronger Overall Privacy
Locking individual apps is powerful, but real privacy comes from layered defenses. Consider these additional practices:
- Use a strong alphanumeric passcode instead of a four-digit code. Go to Settings → Face ID & Passcode → Change Passcode → Passcode Options.
- Disable lock-screen previews for notifications under Settings → Notifications → Show Previews → When Unlocked.
- Turn on Stolen Device Protection (Settings → Face ID & Passcode) so sensitive changes require Face ID with a one-hour delay when away from familiar locations.
- Enable Advanced Data Protection for end-to-end encrypted iCloud backups (Settings → [your name] → iCloud).
- Use encrypted DNS like Cloudflare's 1.1.1.1 profile or NextDNS to prevent network-level tracking of the apps you use.
- Audit App Privacy Reports weekly under Settings → Privacy & Security → App Privacy Report.
- Shorten and mask links you share publicly. Services like Lunyb let you create branded short links that protect destination URLs and offer analytics without exposing your original endpoints.
When Native Face ID Locking Isn't Enough
For most users, the built-in tools cover every realistic scenario. However, certain situations call for additional measures:
Sharing Your iPhone Temporarily
If you're handing your phone to a child or friend to watch one video or play one game, use Guided Access: triple-click the side button inside an app to lock the device into that single app. Exit requires Face ID or your passcode.
Protecting Cloud Backups
Photos in iCloud are encrypted in transit and at rest, but enabling Advanced Data Protection ensures Apple itself cannot decrypt them. Combine this with locked Hidden albums for layered defense.
Sharing Links Privately
When you share a link to a private photo album or document, the URL itself can leak information. Using a privacy-focused shortener like Lunyb obscures the destination and allows you to revoke or password-protect the link later.

Common Mistakes to Avoid
- Reusing your device passcode as the Screen Time passcode. If someone learns your unlock code, they have access to everything.
- Forgetting that screenshots aren't hidden. If you screenshot a locked note, the screenshot lives in your regular camera roll. Move it to the Hidden album immediately.
- Trusting third-party "app locker" apps from the App Store. Most use Shortcuts automations that are easy to bypass. Stick to native iOS features.
- Ignoring notification previews. A locked Messages app still shows new texts on the lock screen unless previews are disabled.
Does This Work on Android?
Android offers similar features under different names. Samsung's Secure Folder, Xiaomi's Second Space, and stock Android's App Pinning all provide biometric-locked containers. Google Photos has a Locked Folder that mirrors Apple's Hidden album functionality. The general principles in this guide apply, but the menu paths differ by manufacturer.
FAQ
Can someone bypass Face ID on a locked app?
Not without your Apple ID password or device passcode. After several failed Face ID attempts, iOS falls back to the device passcode, but the locked app itself requires a separate Face ID success. There is no Settings shortcut to disable the lock without authenticating first.
Will locked apps still receive notifications?
Yes, but the content is suppressed. You'll see that a new notification arrived from the app, but the message preview, sender name, and content remain hidden until you authenticate with Face ID and open the app.
Can I lock the Photos app entirely instead of just the Hidden album?
Yes. Long-press the Photos app icon on your Home Screen and choose Require Face ID. This forces authentication every time anyone opens Photos, not just the Hidden album. Be aware that this may affect how third-party apps access your photo library.
What happens to locked apps when I back up or restore my iPhone?
The Face ID requirement persists through iCloud backups and device transfers. When you restore to a new iPhone, your locked apps remain locked and your Hidden albums remain hidden, provided you sign in with the same Apple ID.
Is there a way to lock individual settings, like Wi-Fi or Bluetooth?
iOS doesn't let you lock individual settings panels with Face ID, but Stolen Device Protection adds a Security Delay to sensitive actions like changing your Apple ID password or disabling Find My. Enabling it under Settings → Face ID & Passcode gives you most of the same protection.
Final Thoughts
Locking apps and photos with Face ID is one of the highest-impact privacy upgrades you can make in under five minutes. The native iOS tools in 2026 are mature, free, and tightly integrated — there is no reason to install third-party app lockers that may compromise the very privacy you're trying to protect. Layer Face ID locking with strong passcodes, disabled lock-screen previews, and encrypted DNS, and your iPhone becomes one of the most personally secure devices in your home.
Start with the apps that hold your most sensitive data — banking, messaging, photos, and notes — and expand from there. Within a week, you'll forget the brief Face ID glance is even happening, but the peace of mind will last.
