Apple requesting Activation Lock passcode for my iPhone 11 even when it's not lost

That is a scam!! Do not interact with the message at all and delete it. Apple will never request that kind of passcode, especially via email. That is a very prevalent scam where thieves will contact the owner of a lost or stolen iPhone, posing as Apple Support, Apple, Police, etc in hopes of them unlocking Activation Lock, and making the iPhone available for use. What's interesting is that you didn't lose your iPhone. But still, scams have no boundaries and we must always stay vigilant.

I can think of two or three scams that the criminals could try to pull off even if "all" that they had was the OP's Apple ID, and Apple ID password, and not physical possession of any of his or her devices.

Absolutely do not respond to such "phishing" attacks!

Hello~ Delete it …don’t interact with it in any way. Scammers doing exactly what scammers do…trying to get you to get involved and once you do it all downhill from there.

No, it is absolutely NOT legitimate.

Apple will NEVER ask you for that.

Fair enough, but the criminal wasn't very smart to send out a lost iPhone message when the OP's iPhone wasn't even lost!
