Questions

## Locking X: questions

### How do I lock X on iPhone?

Touch and hold the X icon on your Home Screen, tap Require Face ID, then confirm with Face ID, Touch ID or your passcode. iPhones with Touch ID say Require Touch ID instead. You need iOS 18 or later. From then on X asks before it opens, and relocks after you quit it.

### Can I hide X on iPhone?

Yes. X comes from the App Store, so after Require Face ID you can tap Hide and Require Face ID, then Hide App. It moves to the locked Hidden folder at the bottom of App Library. Its name still appears in Screen Time, battery usage and App Store purchases.

### Does X have its own lock?

We found no app lock for iPhone in X Corp.'s help center, so Require Face ID is the built-in way to lock X. It works on iOS 18 and later and opens with Face ID, Touch ID or your iPhone passcode, so anyone who knows your passcode can still open it.

### Does locking X hide its notifications?

Apple says information inside a locked app won't appear in notification previews, search, Siri suggestions or CarPlay. The lock applies only to the iPhone where you set it; the locked status doesn't sync to your other devices through iCloud, so lock it on each one.

### How do I lock X on iOS 17 or earlier?

Require Face ID needs iOS 18. Older versions have no built-in way to lock X. Guided Access keeps your iPhone in one app while someone holds it. Updating to iOS 18 or later, if your iPhone supports it, adds Require Face ID.
