WhatsApp's own lock goes further. Published 2026-10-31 - Updated 2026-10-31 - By VaultForYou Editorial Team - Checked against iOS 27 - Oct 31, 2026 ## Quick answer Touch and hold the WhatsApp icon, tap Require Face ID, then tap it again to confirm. WhatsApp then asks for Face ID, Touch ID or your passcode every time it opens. It works on iOS 18 or later and takes about 10 seconds. WhatsApp also has its own lock: Screen Lock. - **Fastest way:** Touch and hold -> Require Face ID -> confirm. - **Own lock:** Screen Lock. - **Opens with:** Face ID, Touch ID or your iPhone passcode. - **Other devices:** The iOS lock doesn't sync. Set it on each device. - **iOS version:** iOS 18 or later - **Time needed:** About 10 seconds - **Difficulty:** Easy - **Needs an app?:** No - **Reversible?:** Yes - **Separate code?:** No iOS can lock WhatsApp with Face ID in about 10 seconds, and WhatsApp adds Screen Lock. Below: 4 ways to lock it, and what each one does and doesn't protect. We checked the iOS steps against Apple's iOS 27 documentation and WhatsApp's settings against its official help pages in October 2026. ## Method 1: Lock WhatsApp with Face ID (iOS 18 and later) 1. **Find WhatsApp on your Home Screen** Touch and hold the WhatsApp icon until the quick actions menu opens. 2. **Tap Require Face ID** On iPhones with Touch ID it says Require Touch ID. Require Passcode is also offered. 3. **Confirm** Tap Require Face ID again and authenticate. WhatsApp now asks for Face ID every time it opens. WhatsApp relocks each time you leave it. Apple says information inside a locked app won't appear in notification previews, search or Siri suggestions. **What this does not do:** your iPhone passcode opens every locked app. So does anyone whose face or fingerprint is enrolled on your phone. ## Method 2: WhatsApp's own lock ### Screen Lock Requires Face ID or Touch ID to open WhatsApp, after a wait time you choose. If Face ID or Touch ID fails, your iPhone passcode unlocks it. You can still reply to messages from notifications and answer calls while it is locked. This lock uses the same Face ID or passcode as your iPhone, so it adds a second prompt, not a second secret. ## iOS lock vs WhatsApp's own lock | | iOS Require Face ID | Screen Lock | |---|---|---| | Opens with | Face ID, Touch ID or iPhone passcode | Face ID, Touch ID or iPhone passcode | | Separate from iPhone passcode | No | No | | Hides notification content | Yes | Depends on the app | | Set where | Home Screen, touch and hold the icon | Inside WhatsApp | ## Method 3: Lock and hide WhatsApp together In the same menu, **Hide and Require Face ID** locks WhatsApp and moves it to the Hidden folder in App Library. See [how to hide WhatsApp](/hide-apps/whatsapp). ## Locking WhatsApp doesn't lock its photos Photos you saved from WhatsApp are in your camera roll, outside the lock. Move them into a vault and delete the originals from Photos. > **Lock this in VaultForYou.** Keep WhatsApp photos in an encrypted vault that opens only with a pattern you draw.

To stop WhatsApp using Face ID for its own sign-in, go to **Settings -> Face ID & Passcode -> Other Apps** and turn it off. ## Frequently asked questions ### Can I lock WhatsApp on my iPhone? Yes. On iOS 18 or later, touch and hold WhatsApp, tap Require Face ID, then confirm. It then needs Face ID, Touch ID or your passcode every time it opens. WhatsApp also has its own lock, Screen Lock. ### How do I lock WhatsApp without Face ID? Use the same menu. On iPhones with Touch ID it reads Require Touch ID, and you can choose your passcode instead. Screen Time with a Screen Time passcode is another option that uses a different code. ### Can someone open WhatsApp if they know my passcode? Yes, if you only use Require Face ID: it accepts your iPhone passcode. To stop someone who knows your passcode, you need a lock with its own separate code, such as a Screen Time passcode. ### Does locking WhatsApp hide its notifications? It hides what's inside them. Apple says information from a locked app won't appear in notification previews, search or Siri suggestions. The icon stays on your Home Screen. To hide the icon too, use Hide and Require Face ID. ### Does a lock on WhatsApp carry over to my iPad? No. Apple says locked and hidden apps don't sync with iCloud. The lock only applies to the iPhone where you set it. Lock WhatsApp separately on your iPad with the same menu (iPadOS 18 or later). ## Bottom line Require Face ID locks WhatsApp in about 10 seconds. WhatsApp's Screen Lock adds a second prompt inside the app. ## Sources - [Apple Support: Lock or hide an app on iPhone](https://support.apple.com/guide/iphone/lock-or-hide-an-app-iph00f208d05/ios) - [Apple Personal Safety User Guide: Lock or hide apps on your iPhone](https://support.apple.com/guide/personal-safety/ipsd0be4c185/web) - [WhatsApp Help Center: Turn chat lock on or off](https://faq.whatsapp.com/764072925284841/?cms_platform=iphone) - [WhatsApp Help Center: How to use Touch ID or Face ID for WhatsApp](https://faq.whatsapp.com/876873509397404/) - [WhatsApp Help Center: How to manage your notifications](https://faq.whatsapp.com/797069521522888/?cms_platform=iphone) - [WhatsApp Blog: Introducing parent-managed accounts](https://blog.whatsapp.com/introducing-parent-managed-accounts-on-whatsapp) ## More WhatsApp privacy guides - [How to hide WhatsApp on iPhone](https://www.vaultforyou.app/hide-apps/whatsapp) - [How to block WhatsApp on iPhone](https://www.vaultforyou.app/block-apps/whatsapp) - [How to hide photos in WhatsApp](https://www.vaultforyou.app/hide-photos/whatsapp) - [WhatsApp privacy on iPhone: every setting](https://www.vaultforyou.app/apps/whatsapp) ## Lock apps for other apps - [How to lock Facebook Messenger on iPhone](https://www.vaultforyou.app/lock-apps/messenger) - [How to lock Signal on iPhone](https://www.vaultforyou.app/lock-apps/signal) - [How to lock Telegram on iPhone](https://www.vaultforyou.app/lock-apps/telegram) - [How to lock LINE on iPhone](https://www.vaultforyou.app/lock-apps/line) - [How to lock Photos on iPhone](https://www.vaultforyou.app/lock-apps/photos) - [How to lock Safari on iPhone](https://www.vaultforyou.app/lock-apps/safari) - [All lock-app guides](https://www.vaultforyou.app/lock-apps) ## The full guide - [How to lock apps on iPhone, with Face ID or without it](https://www.vaultforyou.app/blog/lock-apps-iphone) --- Our guides are written and fact-checked by the VaultForYou team against Apple's own documentation.
