Seed phrase, seed recovery or recovery phrase which is said to be an arrangement of words used to gain access to cryptocurrency wallets. In Bitcoin, seed phrases gives users an avenue to backup their wallets. If one looses access to a certain wallet it can be accessed in any BIP39-compactible wallet to recover funds. We have over 2048 words on the BIP39 word list, this means that a string of 12 words would have 128bits of security. This makes hacking or intruding into your wallet a bit studious.
If an intruder wishes to attack a wallet it is expected of such to carryout 2128 operations to guess a 12 word phrase. It might seem to be a small number, but it is more complex than you think. This seed can also be extended to improve security.
Is seed phrase the same as private key
Seed phrase is different from private key in that private key can be considered to be a secret number that allows coin to be spent. It creates a key pair that grants access to wallets. While a seed phrase is simply a representation of a random number. It's an ordered sequence of 12 or 24 words, chosen from a list of 2048 words. Using cryptography, your wallet can derive your private key using your seed phrase. And with that private key, your wallet can spend your bitcoin.
Seed phrase extensionSeed extension is the process of adding more words to the existing seed phrase to strengthen the security of a crypto wallet. This is done while creating a new wallet.
