Is "those information" valid, or is it "this information"?

I have been teaching it as 'this information' for more than 20 years but just heard a British reporter on Bloomberg say 'these informations' and l had to look it up. There are actually many examples of 'these information' online (and my autocorrect ironically wanted to change that to 'these informations'!!! Lol)

The adjective or article "this" modifies "information," a singular, so "this" is correct. It assumes that the reader knows that "information" is referring to "username and password."

If instead you wish to use "this/those" as pronouns, you might write something like:

The username and password are missing. I need these right away.
