12/24 words recovery phrase not passphrase sorry, I don't want to confuse newbies. Passphrase is the optional password on top of the 12/24 words which will derive an entiery new set of keys, never forget you passphrase if you use one as you will use your bitcoins even if you still have the recovery phrase. But Phoenx doesn't have the option anyway, doesn't make much sense for a hot wallet.
