How can I get my Apple Account verification code?

Perhaps there's more than one method to try/test (get)

a verification code sent to some device or another; to

access and collaborate functions between these items..

On the other hand, words may lose meaning when or if

they've been confused; such as Authenticate vs Verify..

Read carefully since if overly tired or stressed, these are

among things to avoid or resolve quickly to avoid issues.

This is where your device(s) send six-digit code, to other one(s)

to access them; be sure to read & understand when to use them.

Sometimes these may throw you into a loop when your Mac wants

you to enter a Passcode ~ yet only shows a space for Password!!

[Then what? I had this issue; and forgot how I fixed it. 'Admin user'

accounts have passwords. Every level of security is problematic.]
