Find my device

You can use any computer and log into icloud.com/find (note the "/find") and no two-factor code will be needed.

You can also use a friends iPhone and use the following instructions from Locate a lost or stolen device - Apple Support

You can help a friend find their device if it's missing and has Find My [device] turned on:

1. Open the Find My app.
2. Choose the Me tab.
3. Select Help a Friend.
4. Have your friend sign in to iCloud with the Apple ID they're signed in with on their missing device.

You either didn’t read or didn’t understand the post from FoxFifth. If you use this specific URL: https://icloud.com/find it will not require 2 factor authentication. But if you go to https://icloud.com it will require 2FA. You must put the /find at the end of the iCloud URL to bypass 2FA.

Are you sure you didn’t set up an additional phone number to receive the 2FA code when you set it up? The set up procedure strongly encouraged you to.

Thank you for the clarification. He didn't explain that nor did he explain that it would bypass two factor authentication.

Really...? "You can use any computer and log into icloud.com/find (note the "/find") and no two-factor code will be needed."

My wife doesn't listen to what I say either!

Do you listen to what she says?

Of course!

Her opinion on that may vary slightly at times.
