Q: Why am I getting email password verification notifications from iCloud every time I turn on my Macbook Pro?

Hi everyone,

I'm new here so please bear with me.

For the past month or so I have been getting these email password verification notifications from iCloud.

I entered the password, but that doesn't seem to stop it from coming back up.

It happens every time I turn my Macbook on or restart it.

Suggestions on how to make it go away?

Suppose if I were to leave it, what would happen to my Mac in the future?

Thanks in advance!
