Take a domain from "just added to cPanel" to "ready to send email."
Any order, any small words between them — only the four words count. Still on the old four digits? They work here too, until you choose your words.
Check your email for a sign-in link. It works once, and it never changes your pass phrase.
The machine deals four words; you build any sentence you like around them. Tap a word you don't like (or don't know) for another. Only the four words are the credential — order, small words and punctuation are ignored.
