Generate a mnemonic phrase

Generate a 12 or 24-word BIP-39 mnemonic phrase with the Hedera SDK Mnemonic class so you can derive and recover associated private keys later.

Generate a 12 or 24-word mnemonic phrase that can be used to recover the private keys that are associated with it.

Method	Type	Description
Mnemonic.generate24()	Mnemonic	Generates a 24-word recovery phrase that can be used to recover a private key
Mnemonic.generate12()	Mnemonic	Generates a 12-word recovery phrase that can be used to recover a private key

Java

// 24-word recovery phrase
Mnemonic mnemonic = Mnemonic.generate24();
System.out.println("mnemonic 24 word = " + mnemonic);


//12 word recovery phrase
Mnemonic mnemonic12 = Mnemonic.generate12();
System.out.println("mnemonic 12 word = " + mnemonic12);

//v2.0.0

// generate a 24-word mnemonic
const mnemonic = await Mnemonic.generate();

console.log(mnemonic)

//Generate 24 word mnemonic
mnemonic24, err := hedera.GenerateMnemonic()

if err != nil {
  panic(err)
}

privateKey, err := mnemonic24.ToPrivateKey( /* passphrase */ "")

if err != nil {
    panic(err)
}

publicKey := privateKey.PublicKey()

fmt.Printf("mnemonic = %v\n", mnemonic)
