Usually, you can’t unlock an Apple Watch after forgetting its passcode without erasing it. The exceptions are entering the correct passcode or using Unlock with iPhone if it was enabled beforehand and the paired iPhone is nearby. Unlock with iPhone is not a way to recover or reveal a forgotten passcode.
Apple Support says that if you’ve forgotten your Apple Watch passcode, you’ll need to reset the watch and set it up again. If neither no-erasure option applies, erase the watch and restore from an available backup during setup. See Apple’s lock and unlock instructions and forgotten-passcode instructions.
The quick answer: what can and cannot be done
| Your situation | What to do | Will the watch be erased? |
|---|---|---|
| You know the watch passcode | Wake the watch and enter the correct passcode. | No |
| You forgot the passcode, but Unlock with iPhone was enabled beforehand | Unlock the paired iPhone while it is near the watch. | No, if automatic unlocking succeeds |
| You forgot the passcode and automatic unlocking is unavailable or fails | Erase the watch, set it up again, and restore from an available backup if prompted. | Yes |
The paired iPhone does not display or calculate an unknown Apple Watch passcode. Unlock with iPhone is automatic authentication, not passcode recovery. Apple’s documented remedy for a forgotten passcode is to erase or reset the watch and set it up again.
Method 1: Try Unlock with iPhone without erasing the watch
This can work only if Unlock with iPhone was enabled before you were locked out, the watch is still paired with that iPhone, and the iPhone is nearby. Apple says the paired iPhone must be within normal Bluetooth range, about 33 feet (10 meters). If Bluetooth is off on the watch, you must enter the watch passcode to unlock it.

Steps
- Put the watch on your wrist.
- Keep it near the paired iPhone, within normal Bluetooth range.
- Unlock the paired iPhone normally.
- Wait briefly to see whether the watch unlocks.
If it works, you can use the watch without entering its passcode for that session. It does not reveal or replace the forgotten passcode. If the feature was not enabled beforehand, do not rely on turning it on after lockout as a bypass.
If automatic unlocking fails
Check that the paired iPhone is nearby and unlocked, and that Bluetooth is active on the watch. If the watch remains locked, follow Apple’s reset instructions rather than repeatedly guessing.
If Erase Data is enabled, Apple says the watch erases its data after ten failed passcode attempts. This applies only when that setting was turned on. See Apple’s passcode guidance.
Method 2: Reset the Apple Watch from the paired iPhone
If the paired iPhone is available, use the Apple Watch app to erase the watch. Menu wording can vary by software version and region.

- Keep the Apple Watch and paired iPhone close together.
- Open the Apple Watch app on the iPhone.
- Go to My Watch > General > Reset.
- Tap Erase Apple Watch Content and Settings and confirm.
- On a GPS + Cellular model, choose whether to keep or remove the cellular plan based on whether you intend to pair this watch with this iPhone again.
- Set up the watch again and restore from a backup if prompted.
See Apple’s forgotten-passcode instructions.
Method 3: Reset the watch directly without the iPhone
If the paired iPhone is unavailable, reset the watch using its controls. Keep it on its charger throughout the process.
- Place the Apple Watch on its charger and leave it there.
- Press and hold the side button until the power button appears.
- Press and hold the Digital Crown until Erase all content and settings appears.
- Tap Reset, then tap Reset again to confirm.
- Wait for the erase to finish, then set up the watch again and restore from a backup if prompted.
Apple’s official instructions explain this reset process.
Erase versus unpair: they are not the same
| Action | What it does | Best use |
|---|---|---|
| Erase the watch | Erases content and settings; Activation Lock may remain. | You forgot the passcode and intend to keep using the watch. |
| Unpair from the paired iPhone | Erases the watch and removes Activation Lock when completed through the paired iPhone. | You are transferring or selling the watch. |
For a forgotten passcode, follow Apple’s reset instructions. For a transfer, use Apple’s unpair and erase guide.
What happens to your data after an erase?
Erasing removes the watch’s content and settings. Apple says a backup is created on the iPhone before the watch-side erase and its reset instructions offer restoration during setup. A backup may restore content, but it is not a guarantee that every item or the latest state can be recovered.

Activation Lock: have your Apple Account credentials ready
Activation Lock is separate from the forgotten watch passcode. Erasing without unpairing can leave Activation Lock in place, and you may need the Apple Account credentials used to set up the watch to activate it again. Erasing does not make a watch available to anyone who finds or buys it.
If setup asks for a previous owner’s Apple Account, ask the seller to remove the watch from their account. Do not try to bypass Activation Lock.
Why there is no universal no-reset bypass
Apple documents entering the known passcode or using Unlock with iPhone when it was enabled beforehand as the no-erasure options. If you forgot the passcode and neither option works, Apple’s documented route is to erase the watch and set it up again. Do not treat third-party tools or alleged tricks as supported or verified passcode recovery methods.
If you know the passcode and want fewer manual entries
If you can enter the current passcode, you can enable Unlock with iPhone for future use:

Does my Apple Account password unlock a locked Apple Watch?
No. Apple Account credentials are separate from the watch passcode and may be needed for Activation Lock after an erase.
How many incorrect passcode attempts erase an Apple Watch?
Apple says data is erased after ten failed attempts only if Erase Data was enabled. Do not assume this setting is on for every watch.
The bottom line
You can avoid erasing the watch if you know its passcode or if Unlock with iPhone was already enabled and works with the paired iPhone nearby. If you forgot the passcode and automatic unlocking fails or was never configured, Apple’s documented route is to erase the watch, set it up again, and restore from an available backup if prompted.
