Someone Keeps Going Through Your Phone: How to Stop It
Someone you live with keeps going through your phone. When it happens again and again, they have a reliable way in: they know your passcode, they find the phone unlocked, or they use your face. Close each route, then decide what to say.

What do I need to know?
- Find the route first. A new passcode does nothing if they pick the phone up while it is still unlocked.
- Most fixes take minutes and are all in iOS settings.
- Keep the most private things behind a second lock that is not your passcode.
How do they keep getting in?
Think about when it happens.
- While you are out of the room: the phone was unlocked, or they know the code.
- While you sleep: they may hold the phone up to your face.
- Even after you changed the code: they watched you type it, or added their own face to Face ID.
If you are not sure it is happening, our guide on telling if someone went through your iPhone covers Screen Time and the Recently Viewed album.
How do I close each route on iOS 27?
- Change your passcode and type it with the screen covered. Settings → Face ID & Passcode → Change Passcode (Apple).
- Reset Face ID if you did not set up an alternate appearance yourself. Settings → Face ID & Passcode → Reset Face ID, then set it up again (Apple).
- Turn on Require Attention for Face ID. Settings → Accessibility → Face ID & Attention. Apple says the phone then unlocks only when your eyes are open and looking at the screen (Apple).
- Lock it before you put it down. Holding the side button and a volume button for 2 seconds, then pressing the side button, locks it and needs the passcode next time (Apple).
- Hide message previews. Settings → Notifications → Show Previews → When Unlocked (Apple).
- Check your Apple Account devices. Settings → your name, then scroll to the device list. Remove anything you do not recognise (Apple).
What about things they have already seen?
Changing settings stops the next look, not the last one. Move the photos and notes you care most about into something with its own lock. Then delete the originals and empty Recently Deleted in Photos.
Should I say something?
With a housemate or a sibling, a plain request often works: "Please do not use my phone without asking." Say it once, calmly, after the settings are changed. Then it is about the boundary, not about catching them.
If it is a parent and you are a teen, their rules may be different. Talking to another adult you trust can help.
What if it is about control?
If a partner checks your phone to see who you talk to, demands your code, or gets angry when you lock things, that is a warning sign. Changing settings can be noticed, so think about timing. Safety Check in Settings → Privacy & Security has an Emergency Reset and a Quick Exit button (Apple).
The National Domestic Violence Hotline (US) can help you plan, including around phones. In danger, call your local emergency number.
What this doesn't protect against
None of this helps if you hand over the unlocked phone, or someone forces you to unlock it. Someone who uses your phone can still see that a vault app is installed. A vault cannot stop a person who watches you draw your pattern.
Do it with Cryptile
Cryptile vaults open with a pattern, not your passcode, so knowing the code does not open them. A different pattern opens a different vault, and nothing lists them. Auto-lock closes an open vault when you leave the app.
Cryptile is free for up to 2 vaults, 100 photos and 10 videos. Plus removes the limits for $19.99 a year (7-day free trial) or $39.99 once. The price is the same every day.
