# Seed Phrase vs Private Key

A [seed phrase](/glossary/definitions/self-custody-wallets/seed-phrases.md) (also known as a recovery phrase, mnemonic phrase, or backup phrase) is a sequence of words that are used to restore a [self-custody wallet](/glossary/definitions/self-custody-wallets.md). It typically consists of 12-24 words that are generated when the wallet is first created. The seed phrase can be used to recreate the wallet and access the funds stored in it, so it is important to keep it safe and secure.

A [private key](/glossary/definitions/self-custody-wallets/private-keys.md), on the other hand, is a long string of letters and numbers that is used to access and manage a self-custody wallet. It is typically a 64-character hexadecimal code that is generated along with the wallet's address. The private key is used to sign transactions on the blockchain, so it is also important to keep it safe and secure.

The main difference between a seed phrase and a private key is their purpose. A seed phrase is used to restore a wallet, while a private key is typically used to access and manage the funds in a wallet. Another key difference is that a seed phrase is typically a sequence of words that is easier for a human to remember, while a private key is a long string of letters and numbers that is not as easy to remember.
