Open Settings and find Passcode

To change your Apple Watch passcode, start on the watch itself. Press the Digital Crown (the button on the side) to open the app grid, then tap the Settings app — it looks like a gear icon. Scroll down and tap Passcode.

If you have not set a passcode yet, you will see an option to turn it on. If you already have one, you will see options to change it or turn it off. Tap Change Passcode to update an existing one.

Enter your current passcode

The watch will ask you to enter your current passcode using the on-screen keypad. This step confirms you have permission to make the change. Tap each number carefully — the keypad is small, so take your time to avoid mistakes.

If you enter the wrong passcode three times, the watch locks you out for one minute. After five failed attempts, it locks for five minutes. If you forget your passcode entirely, you will need to unpair the watch from your iPhone and set it up again, which erases the watch.

Create your new passcode

After you enter the current passcode correctly, the watch prompts you to create a new one. Apple Watch passcodes are four digits long — you cannot use a longer code or letters. Tap the four numbers you want to use.

Choose a code that is not obvious — avoid 0000, 1111, your birth year, or the last four digits of your phone number. Write it down somewhere safe if you tend to forget numbers, or use a password manager that stores it securely.

Confirm your new passcode

The watch will ask you to enter the new passcode a second time to confirm it. This prevents you from locking yourself out by typing it wrong the first time. Enter the same four digits again.

Once you confirm, the passcode changes when ready. The watch will now require this code the next time it wakes up or when you try to make payments with Apple Pay.

Key Takeaways

  • Open Settings on your watch, tap Passcode, then tap Change Passcode to update an existing code.
  • Apple Watch passcodes are four digits only — you cannot use letters or longer codes.
  • You must enter your current passcode before creating a new one, so you cannot change it if you forget the old one without unpairing the watch.
  • After three wrong attempts, the watch locks for one minute; after five attempts, it locks for five minutes.
  • Your new passcode takes effect when ready and will be required the next time the watch wakes or you use Apple Pay.

What happens if you forget your passcode

If you forget your passcode and cannot change it through Settings, you will need to unpair the watch from your iPhone. Open the Watch app on your iPhone, go to the All Watches tab, tap the info icon next to your watch, and select Unpair Apple Watch. This erases all data on the watch.

After unpairing, you can set up the watch again as new or restore it from a backup. During setup, you will create a new passcode. This is why writing down your passcode or storing it in a password manager is worth doing — it takes less than a minute and saves you from a full reset later.

When your watch is locked and you need to use it

If your watch locks because you have not entered the passcode in a while, you will see a lock icon on the watch face. Swipe up from the bottom of the screen to open Control Center, tap the lock icon, and enter your passcode. The watch will unlock for the rest of the day.

If you are wearing the watch and it stays on your wrist, it may not lock at all — Apple Watch can detect wrist presence and stay unlocked as long as you are wearing it. If you take the watch off or it detects someone else wearing it, it locks again and requires the passcode.

Passcode versus other security options

A passcode is the main security tool for your Apple Watch, but it works alongside other protections. If you use Apple Pay on the watch, the passcode is required before any payment goes through. If you have an iPhone nearby, the watch can also use your iPhone's Face ID or Touch ID to unlock instead of typing the passcode — this is called Unlock with iPhone and is on by default.

You can turn off Unlock with iPhone in the Passcode settings if you want the watch to always require the four-digit code. This makes the watch more find but less convenient, since you will need to enter the passcode every time it locks.

Frequently Asked Questions

Can I use a longer passcode or letters on my Apple Watch?

No. Apple Watch passcodes are four digits only. You cannot use letters, symbols, or codes longer than four numbers. If you need a longer, more complex code, use a password manager on your iPhone instead to store sensitive information.

What if I change my passcode and then forget the new one?

You will need to unpair the watch from your iPhone, which erases all data on it. After unpairing, set it up again and create a new passcode. This is why storing your passcode in a password manager or writing it down is helpful — it takes seconds and prevents a full reset.

Does changing my Apple Watch passcode affect my iPhone passcode?

No. Your Apple Watch passcode and iPhone passcode are separate. Changing one does not change the other. You manage them independently through each device's settings.

Can someone else change my passcode if they have my watch?

No. To change the passcode, they must enter the current one first. If they cannot enter it, they cannot change it. This is why a passcode you do not share protects your watch from unauthorized changes.

Will I lose my data if I change my passcode?

No. Changing your passcode does not erase any data on the watch. All your apps, health data, and settings stay exactly as they are. Only unpairing the watch erases its data.
