Your partner knows your passcode

Updated 3 November 2026 · By the FirstHour team

Short answerLots of couples share passcodes, and that can be fine if you both chose it. Just know how much it opens: your photos, your Hidden album, your apps, and possibly your saved passwords. If you'd like more privacy, change it and tell them, if that's safe. If you're afraid of your partner, talk to a local support service or the police first, because they may notice.

A new passcode can be noticed. The first time your partner tries the old one, they'll know. So can a new lock, a Face ID that no longer opens for them, or pictures that have gone. Apple's own safety guide warns that changes to sharing or access may be noticed by others. If someone demands your passcode, checks your phone in a way that frightens you, or you think a change could make things worse, talk to a local support service or the police before you change anything.

What your passcode opens

If you'd like it changed

It can be a short, ordinary talk: "I'm changing my passcode, and I'd like to keep it to myself." You don't owe anyone a passcode, and wanting one doesn't mean you're hiding something. Only have this talk if you feel safe doing it.

  1. Change it. Go to Settings, tap Face ID & Passcode (or Touch ID & Passcode), enter your passcode, and tap Change Passcode. Choose something they wouldn't guess, not a birthday or anniversary.
  2. Tap Review Access if it appears. It checks settings that could still let someone in.
  3. Close the 72-hour gap. Apple says that for 72 hours, your old passcode can still reset the new one. If you don't want that, go back to Face ID & Passcode and tap Expire Previous Passcode. If you do, you can't use the old one if you forget the new one.
  4. Check Face ID. An alternate appearance could be someone else's face. Apple's guide doesn't show a way to see who's on it, so the fix is to tap Reset Face ID and set it up again. On an iPhone with Touch ID, look for fingerprints that aren't yours.
  5. Check your Apple Account. If they might know the password, go to Settings, tap your name, then Sign-In & Security, then Change Password. Apple sends an alert when the password changes, and anyone still signed in may see it. Then look at the device list on the first screen and remove what shouldn't be there. Apple says to review this if someone else had access to your password.
  6. Run Safety Check. It's in Settings, Privacy & Security. Manage Sharing & Access goes through what you share with people and apps, one at a time, including location. It can't review accounts outside Apple, so change other important passwords on their own.

If you're keeping things as they are

That's a fair choice. You could still move private details out of Photos, such as a picture of a card. Here's how to find those. It's also worth agreeing what happens if things change between you.

How FirstHour helps

The Vault has its own pattern or PIN, separate from your iPhone passcode, so knowing your passcode isn't enough to open it, and neither is Face ID. A well-chosen pattern can be much harder to guess than a 6-digit PIN. But someone who sees you draw it can copy it, and that's more likely with someone you live with. Keep your recovery phrase somewhere they won't find it, because anyone who has it can open the Vault.

Questions

Will they be told I changed it?

Your iPhone's passcode change isn't announced as far as we can find, but they'll notice when the old one stops working. Apple says it notifies you of Apple Account password changes, so anyone who can see those alerts may notice that too.

What about someone else who knows it, such as a friend?

The same steps work. Someone knows my passcode covers that, and this one is for a thief.
