A seed phrase, also known as a mnemonic phrase or backup phrase, is a string of words used to generate and restore a private key in a cryptocurrency wallet.
The seed phrase is used to store the key securely and serves as a backup in case the user loses access to their wallet. The phrase is usually made up of 12-24 random words and is generated by the wallet software. The seed phrase is considered a critical component of wallet security and should be kept confidential and stored in a safe place. If a user loses access to their wallet, they can use the seed phrase to restore the private key and access their funds. Overall, a seed phrase is an essential tool for managing and securing cryptocurrency assets.
