Is this authentication request legitimate?

This pop-up shows up on my desktop occasionally.

The icon is associated with the weather app Tomorrow.io, but that may have no relation to the pop-up.

So, is this a legitimate request?

Note: that my various Apple media apps show that I am signed in.

No. Don’t enter it. Maybe it is needed for synch.
But apps, if they need access to the iCloud, sometimes ask for a app specific password, but not for the password of your iCloud account.
