Here’s a scenario that probably sounds familiar: your phone lights up on the table during a meeting, and suddenly everyone nearby can read your text message before you even touch it. Whether it’s a personal conversation, a two-factor authentication code, or just something you’d rather keep private, that’s not great.
By default, iPhones show the full content of your texts and iMessages right on the Lock Screen, even if you have Face ID, Touch ID, or a passcode set up. The good news is that iOS gives you a surprising amount of control over this. You can hide just the message text, hide everything entirely, or go full stealth mode where no one even knows you got a message. In this guide, I’ll walk you through all your options so you can pick what works best for you.
Quick note: None of these settings will fully protect you if your phone has no passcode, Face ID, or Touch ID set up. If someone can just swipe to unlock your phone freely, they can open Messages and read everything. Make sure you have some form of lock screen security enabled first.
Why Lock Screen Previews Are a Real Privacy Problem
It’s easy to shrug this off, but consider what actually shows up on your Lock Screen by default. The full text of a message, the sender’s name, and sometimes even a photo. Anyone standing near you, or anyone who glances at your phone on your desk, can read it all without touching a thing.
There’s also the two-factor authentication angle, which is a big one. Lots of websites and apps send you a login code via text message. If that code shows up on your Lock Screen in plain view, someone nearby could grab it and use it to access your accounts, even while your phone is still locked. That’s a pretty serious security risk hiding in plain sight.
Option 1: Hide Message Previews for All Apps (Global Setting)
This is the quickest fix if you want to lock things down across the board. Not just for Messages, but for every app that sends notifications. iOS has a single global Show Previews setting that controls whether notification content appears on your Lock Screen for all apps at once.
Step 1: Open Settings and Tap Notifications
Open the Settings app on your iPhone, then tap Notifications.
Step 2: Tap “Show Previews” at the Top
Near the top of the Notifications screen, you’ll see a Show Previews option. Tap it.
Step 3: Choose Your Privacy Level
You’ll see three options:
- Always, The default. Message content shows on the Lock Screen for everyone to see.
- When Unlocked, Notification content is hidden until you unlock your phone with Face ID, Touch ID, or your passcode. This is the sweet spot for most people. On Face ID iPhones, previews will even “expand” automatically once the camera recognizes your face, which is pretty clever.
- Never, Message content is never shown in notifications, period. You’ll see that you have a message, but you’ll have to open the app to read it.
Select When Unlocked or Never depending on how private you want to be.
Option 2: Hide Previews Just for the Messages App
Maybe you’re fine with other apps (like Calendar or Mail) showing previews, but you specifically want to keep your texts private. No problem. iOS lets you override the global setting on a per-app basis. Here’s how to do it just for Messages.
Step 1: Go to Settings > Notifications > Messages
Open Settings, tap Notifications, then scroll down to the Notification Style section and tap Messages.
Step 2: Tap “Show Previews” in the Lock Screen Appearance Section
Scroll down to the Lock Screen Appearance section and tap Show Previews.
Step 3: Pick Your Setting
Same three options here, Always, When Unlocked, or Never, but this time it only applies to Messages. Your other apps will keep whatever the global setting is.
This is a great middle ground if you want the convenience of seeing other notifications but want your texts kept private.
Option 3: Turn Off Messages Notifications on the Lock Screen Entirely
If hiding the preview text isn’t enough and you don’t want anyone to even know you received a message, you can go further. This removes the notification from the Lock Screen completely, though you’ll still get sounds, badges, and banners once you unlock your phone if you want them.
Step 1: Go to Settings > Notifications > Messages
Open Settings, tap Notifications, then tap Messages.
Step 2: Disable Lock Screen Alerts
Under the Alerts section, you’ll see checkboxes for Lock Screen, Notification Center, and Banners. Uncheck Lock Screen to stop message notifications from appearing there while keeping banners and sounds active when you’re using your phone.
Or, if you want to go full stealth, toggle off Allow Notifications at the very top. Fair warning: you won’t get any alerts at all, no sound, no badge, nothing. You’d have to open the Messages app manually to check for new texts. That’s probably overkill for most people, but the option is there.
Watch Out for Text Message Forwarding
There’s one more privacy angle worth mentioning. Text Message Forwarding is an iOS feature that lets other Apple devices (like a Mac or iPad) signed into the same Apple ID send and receive your text messages. Super convenient, but it also means your texts could be popping up on a shared family computer or a device you forgot to secure.
To check which devices have access to your messages:
- Open Settings and tap Messages.
- Tap Text Message Forwarding.
- Review the list of devices. Toggle off any device you don’t want receiving your messages.
If you have a Mac that you share with others, or an old iPad sitting around the house, it’s worth checking this list. Your texts might be landing there too.
What About WhatsApp, Signal, and Other Messaging Apps?
The good news is that the same Show Previews controls work for third-party messaging apps too. Apps like Signal, WhatsApp, and Telegram all send notifications through iOS, so the same settings apply.
To hide previews for a specific app like WhatsApp, just go to Settings > Notifications > WhatsApp > Show Previews and set it to When Unlocked or Never. Many of these apps also have their own in-app privacy settings that let you show “New message” instead of the actual content, so it’s worth exploring in the app’s settings too.
Tips and Troubleshooting
Common Issues
Problem: I can still see the sender’s name even after hiding previews.
Hiding previews stops the message content from showing, but the sender’s name and app name may still appear. To hide everything, you need to disable Lock Screen alerts for Messages entirely (Option 3 above) or turn off Allow Notifications.
Problem: I set “When Unlocked” but I’m still seeing message text on the Lock Screen sometimes.
On Face ID iPhones, if Face ID recognizes you while a notification arrives, the phone considers itself “unlocked” and shows the preview. To prevent this completely, switch to Never for Show Previews.
Problem: I changed the global Show Previews setting but Messages still shows the full text.
Per-app settings override the global setting. Head to Settings > Notifications > Messages > Show Previews and make sure it’s set to match what you want. It might have been set to Always individually.
Problem: I’m not getting any text notifications at all now.
You may have accidentally turned off Allow Notifications for Messages instead of just adjusting previews. Go to Settings > Notifications > Messages and make sure Allow Notifications is toggled on, then adjust Show Previews separately.
Pro Tips
- Use Focus Modes for extra control: iOS Focus modes (like Do Not Disturb or a custom Personal focus) let you filter which contacts and apps can notify you and how. It’s another useful layer of lock screen privacy on top of preview settings.
- The sweet spot for most people: Set global Show Previews to When Unlocked and make sure you have Face ID or Touch ID enabled. You’ll still get notified, but the content stays hidden until it’s really you looking at the screen.
- Mute specific conversations: In the Messages app, you can swipe left on any conversation and tap the bell icon to hide alerts for that thread. Handy if you only need privacy around certain senders.
Wrapping Up
Keeping your texts off the Lock Screen is one of those small privacy wins that’s genuinely worth doing, especially if you ever leave your phone on a desk, use it in public, or rely on SMS for two-factor authentication codes. The When Unlocked setting is the best balance for most people: you still get notified, but nobody can read your messages without unlocking your phone first. If you want to go further, turning off Lock Screen alerts entirely gives you maximum privacy without completely silencing your notifications.
Once you’ve got your Message previews sorted, it’s also worth reviewing your other notification settings. You might be surprised how much personal info is floating around on your Lock Screen from other apps too.
