A Bitcoin seed phrase serves as a simplified representation of a wallet backup.
A seed phrases consists of a sequence of 12 to 24 words, generated using cryptographic algorithms.
Seed phrases are the foundation of most Bitcoin wallets.
Most wallets generate an entire tree of private key pairs from a single seed, providing a convenient way to manage multiple addresses and private keys.
Seed phrases differ from private keys in their format and functionality.
While a private key is a long string of alphanumeric characters, a seed phrase comprises human-readable words, making it easier for users to remember and transcribe accurately.
Private keys directly control access to the cryptocurrency stored in a wallet, while seed phrases are used to generate those private keys deterministically.
Due to their pivotal role, seed phrases must be stored securely.
If a seed phrase falls into the wrong hands, the attacker gains control over all associated private keys and the cryptocurrency within the wallet.
Consequently, users are advised to keep their seed phrases offline, preferably on physical paper or a secure steel or metal wallet. Storing seed phrases digitally or sharing them online exposes users to hacking risks and potential loss of funds.
