Am I supposed to type my iCloud email AND password in the same text box???

I don’t know if anyone else’s phone is doing this, I’ve never seen this before.

so I’m setting up my daughters iPhone, and my phone also did it earlier too....I keep getting first: a password request to download an app and then 2nd: another request for the iCloud email AND password but there is only ONE Text box to type. I’m so lost. And I put both and nothing. Says it’s wrong. Am I trippin???? Someone help please so frustrating
