You by no means have to give your real information.
I recommend using something like Bitwarden's passphrase generator so all your answers are things like `concise myth bird`.
This way they are A: actually secure, and B: easily pronounceable, so that just saying "a bunch of letters and numbers" to a phone tech shouldn't work as I've heard people complain can happen when using normal passwords (e.g., c9b21s1qzs) for these fields.
