I accidentally locked my macbook air through my phone, they didn't ask me for any lock code, and now the macbook requires some kind of password. I can't enter it correctly. There is no unlock function through the phone either.

Thanks for posting in the Apple Support Communities!

Check out the following information for assistance with unlocking your Mac. You can also locate this information via the following resource if you'd like: If your Mac is lost or stolen - Apple Support

If you can't unlock your Mac

After you locate your Mac, you can unlock it by entering the passcode that you created when you locked it with Find My.

If you can't remember that passcode, you have three options:

• Sign in to iCloud.com/find, then select your Mac from the Devices menu. Select Unlock and follow the steps to verify your identity.

• Unlock your Mac from your iPhone, iPad, iPod touch, or Apple Watch using your device passcode.

• Take your Mac to an Apple Authorized Service Provider along with your proof of purchase.

We hope this is able to clear up what you're seeing.

Cheers!
