A mnemonic phrase, also known as a recovery phrase or seed phrase, is a sequence of words used to recover a cryptocurrency wallet. It's typically generated by the wallet when it's first set up and consists of 12 to 24 words in a specific order. A passphrase, on the other hand, is an additional layer of security that can be added to the mnemonic phrase to further protect the wallet.
