The old 'popup' login box has been removed. I also noticed that the in sub logins where they used to have username/password entry boxes have been removed.
More reddit enshitification to try and make us use their horrible UI.
Not only that but reddit isn’t allowing you to make new accounts as of today, without having a Gmail account first.
What? So you can't use any other email provider but Google to sign up for a Reddit account?
EDIT: I actually don't think this is correct. I just went to the sign up page and it does have buttons to create an account using Google or Apple OAuth (I assume) but there is a field under those two buttons for just any email. Put in my Outlook.com email and it accepted it and went to the next page where I could create my user name and password.
You and everyone replying to you is wrong, the reddit sign up UI is misleading but it doesn't require an email. You can just click "next" on the email prompt without entering anything.
