Some crypto wallet software requires you to have a “seed phrase” as an extra security measure. A seed phrase, also known as a “recovery phrase”, is a list of random words that allow you to recover your wallet in an emergency. Like a master password! A seed phrase is used to access your whole wallet, which can hold multiple public and private keys, so you must keep it secure. Under no circumstances should you share your seed phrase.  Many suggest writing it down on a piece of paper, keeping it off the internet entirely!
