To restart your Apple Watch, follow these steps: Any junk memory or random bugs that may have caused the Auto Unlock issue can be removed by restarting both your Apple Watch and your Mac.

Configure two-factor authentication in iCloud: Either you never turned on two-factor authentication, or you’re still using Apple’s old two-step verification method.
If your Mac doesn’t have a passcode, there’s no need to unlock it.
Enable the password on the both devices: This is self-evident.
Connect both devices to the same iCloud account: Capabilities that rely on Apple’s environment can only be used if all of the devices have the same Apple ID.
You’ll need macOS Sierra or later for your Mac. However, if you have a Series 3 or higher, you must be running watch OS 4 or later.
Upgrade your watchOS and macOS: The Series 0, 1, and 2 require watchOS 3 or later.
Compatibility with the Mac: The Auto Unlock option is available on all Apple Watch variants, but it is only compatible with Macs made of 2013 or later.
