I’ve started getting daily requests to change my Apple ID password .

The call is a scam. Apple will never call you unless you called them and asked for a call back.

You might want to consider changing your password and making sure it is a strong one. You can also add 2 Factor Authentication to your account for more security. If the attempts continue, you might want to consider a name change.
