Because the private key is composed of 64-bit hexadecimal, which is inconvenient to record and copy. For users' convenience, mnemonic was generated. It is simplified into a mnemonic consisting of 12 words, with a space between each word. The mnemonic and private key have the same function, that is, you can import the wallet by entering the mnemonic and setting a new password. Like the private key, a wallet has one set of mnemonics and cannot be modified. Anybody else who discovers the phrase can steal the cryptos, so it must be kept safe like jewels or cash. For example, no one should ask you for it on social networks or messenger, it must not be typed into any website. {% embed url="" %} #### ✅Summary A mnemonic phrase is a **critical component of wallet security**. It simplifies private key management while maintaining full control over a wallet. Proper protection and offline storage of your mnemonic phrase are essential to ensuring long-term security and access to your digital assets.
