What is a private key?

A private key is a secret cryptographic code that proves your ownership of Bitcoin and authorizes transactions from your wallet — a critical element of bitcoin security. Anyone who has your private key can spend your Bitcoin, so it must be kept secure and never shared. Most modern wallets generate a recovery phrase (seed phrase) that represents your private keys in a human-readable format for backup purposes.
