I received two texts with “my apple ID code”, but I didn’t make the request. What does this mean? What do I do?

Someone may be trying to sign your Apple ID, which would generate the request for a verification code. Since you have 2 Factor Authentication enabled, as long as they can't access one of your trusted devices, they can't get a code, and sign in. You should be okay.

They would need to posses the device. It is very unlikely they could hijack a device since you have all of the devices in your possession.

You are welcome.
