Your Partner Knows Your iPhone Passcode: What It Opens
Your partner knows your iPhone passcode. With it and your phone, they can open almost everything, including locked apps and the Hidden album. Changing the passcode closes that door. A vault with its own pattern keeps chosen photos closed, even if you share the new code.

Plenty of couples share passcodes and are fine with it. This page is for when you want some things to stay yours.
What do I need to know?
- The passcode opens the locks. Apple's locked apps and the Hidden collection unlock with Face ID, Touch ID or the passcode.
- Face ID can learn a second appearance. Check that you set up any alternate appearance yourself.
- Some sharing outlives a new passcode. Location sharing and shared albums keep going until you stop them.
What does my passcode open?
On iOS 27, Apple says a locked or hidden app opens with Face ID, Touch ID or your passcode. The Hidden and Recently Deleted collections work the same way. So someone holding your unlocked phone, or knowing the code, gets past all of them.
What should I check today?
- Change the passcode. Settings → Face ID & Passcode → Change Passcode (Apple).
- Check Face ID. If an alternate appearance was set up and you did not do it, tap Reset Face ID and set it up again (Apple).
- Review sharing. Go to Settings → Privacy & Security → Safety Check → Manage Sharing & Access (Apple). It covers location in Find My, shared Photos, Notes and Calendar, and app permissions.
- Move private photos into a vault with its own key. Delete the originals and empty Recently Deleted.
If Stolen Device Protection is on, changing the passcode away from a familiar place adds a one-hour delay (Apple). At home there is no delay.
What if my partner asks why?
Wanting a private space is normal. A short honest answer often works better than a secret change they find later. You might keep sharing the passcode and use a vault only for what is yours.
What if I don't feel safe?
If your partner checks your phone, tracks you or pressures you for access, changing settings can be noticed. Think about timing first. Safety Check includes Emergency Reset, which quickly resets sharing and access.
The National Domestic Violence Hotline (US) can help you plan safely, including around phones. Its site has a button to leave the page quickly. In danger, call your local emergency number.
What this doesn't protect against
Safety Check cannot review shared passwords, social media or anything shared from another device. A partner who can unlock your phone could still see a vault app is installed. If they watch you draw your pattern, they know it too.
Do it with Cryptile
Cryptile opens with a pattern, not your passcode, so a known passcode does not open it. A different pattern opens a different vault, and nothing lists the vaults.
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.
