The fastest way to unlock your Apple Watch

If your Apple Watch is locked with a passcode, you unlock it by entering that passcode on the watch face itself. Raise your wrist to wake the screen, swipe up from the bottom, tap the lock icon, and enter your four-digit code using the digital dial that appears. The watch unlocks immediately and stays unlocked while you wear it — it locks again automatically when you take it off your wrist for more than a few minutes.

If you have forgotten your passcode, you will need to erase the watch and set it up again. This erases all data on the watch but does not affect your iPhone. You can restore your watch settings and apps from your iPhone backup after you erase it.

Key Takeaways

  • A passcode-locked Apple Watch unlocks by swiping up, tapping the lock icon, and entering your four-digit code on the watch itself.
  • The watch automatically locks again when you remove it from your wrist, usually within a few minutes of inactivity.
  • If you forget your passcode, you must erase the watch through the Apple Watch app on your iPhone, then set it up again.
  • Erasing the watch removes all data from the device but does not delete anything from your paired iPhone.

How to set up a passcode in the first place

Open the Apple Watch app on your iPhone and go to Privacy. Tap Passcode and toggle it on. You will be prompted to create a four-digit code. Write this code down somewhere safe — if you lose it, erasing the watch is your only option.

Once the passcode is on, your watch locks whenever it is off your wrist. You do not need to manually lock it. The watch detects when you remove it and locks automatically after a short delay.

Unlocking with your iPhone instead

If you have your iPhone nearby, you can unlock your Apple Watch through the Apple Watch app without entering the passcode on the watch itself. Open the Apple Watch app on your iPhone, go to Privacy, and tap Unlock with iPhone. This temporarily disables the passcode lock on the watch so you can use it without entering the code.

This feature is useful if you forget your passcode temporarily, but it only works when your iPhone is in range and unlocked. The watch will lock again the next time you take it off your wrist.

What to do if you forgot your passcode

There is no way to recover a forgotten passcode. You must erase the watch and start over. Open the Apple Watch app on your iPhone, go to General, then About, and scroll to the bottom. Tap Reset, then choose Erase Apple Watch Content and Settings. This removes everything from the watch.

After the erase completes, you can set up the watch again from scratch. If you had a backup of your watch settings saved to iCloud, you can restore from that backup during setup. If not, you will need to reinstall your apps and reconfigure your settings manually.

Removing the passcode entirely

If you decide you no longer want a passcode on your watch, you can turn it off through the Apple Watch app on your iPhone. Go to Privacy, tap Passcode, and toggle it off. The watch will no longer lock when you remove it from your wrist.

Turning off the passcode does not erase any data. Your watch settings, apps, and information remain exactly as they were. You can turn the passcode back on at any time.

Why your watch might be locked and you cannot unlock it

If your watch is locked and you cannot enter the passcode — for example, the screen is unresponsive or frozen — try a force restart. Press and hold both the side button and the digital crown for about 10 seconds until you see the Apple logo appear on the screen. Release both buttons and wait for the watch to restart.

If the force restart does not work and you still cannot unlock the watch, you will need to erase it through the Apple Watch app on your iPhone using the steps described above. A force restart does not erase data; it only restarts the operating system.

Unlocking a watch you just received or switched to

When you first pair a new Apple Watch with your iPhone, you have the option to restore from a backup or set it up as new. If you restore from a backup of your old watch, the passcode transfers over automatically — you unlock it the same way you did on your previous watch.

If you set up the watch as new, you can add a passcode immediately or skip it for now. You can add one later through the Apple Watch app on your iPhone whenever you want.

Frequently Asked Questions

Does my Apple Watch stay unlocked all day once I unlock it?

No. The watch stays unlocked only while you are actively wearing it. Once you remove it from your wrist, it locks automatically after a few minutes. When you put it back on, you need to unlock it again by entering your passcode.

Can someone else unlock my Apple Watch if they know my passcode?

Yes, if they have physical access to the watch and know your four-digit code, they can unlock it. The passcode is the only security measure on the watch itself. If you are concerned about this, keep your passcode private and consider using a code that is not easy to guess.

What happens to my data if I erase my Apple Watch?

All data stored on the watch — apps, settings, health data, and messages — is deleted. However, your iPhone keeps its own copy of most of this information. After you erase and set up the watch again, you can restore from your iCloud backup to get your settings and apps back.

Can I unlock my Apple Watch with Face ID or Touch ID?

No. Apple Watch uses only a four-digit passcode for security. There is no biometric unlock option like Face ID or fingerprint recognition on the watch itself.

Why does my watch lock so quickly when I take it off?

This is a security feature. The watch assumes that if it is not on your wrist, someone else might be using it, so it locks to protect your information. You can turn off the passcode entirely if you do not want this behavior, but then your watch will have no lock at all.
