{% include note.html content="The personal namespace will be deprecated in the very near future." %}

The personal API managed private keys in the key store. It is deprecated in favour of using [Clef](/docs/tools/clef/Introduction) for interacting with accounts Please refer to the [ns_personal deprecation page](/docs/interacting-with-geth/rpc/ns_personal_deprecation) to see the equivalent methods. The following documentation should be treated as archive information and users should migrate tousing Clef for account interactions.

```

## personal_openWallet {#personal-openwallet}

Initiates a hardware wallet opening procedure by establishing a USB connection and then attempting to authenticate via the provided passphrase. Note,
the method may return an extra challenge requiring a second open (e.g. the Trezor PIN matrix challenge).

| Client  | Method invocation                                               |
| :------ | --------------------------------------------------------------- |
| Console | `personal.openWallet(url, passphrase)`                          |
| RPC     | `{"method": "personal_openWallet", "params": [string, string]}` |

## personal_unlockAccount {#personal-unlockaccount}

Decrypts the key with the given address from the key store.

Both passphrase and unlock duration are optional when using the JavaScript console. If the passphrase is not supplied as an argument, the console will prompt for
the passphrase interactively. The unencrypted key will be held in memory until the unlock duration expires. If the unlock duration defaults to 300 seconds. An explicit duration of zero seconds unlocks the key until geth exits.

The account can be used with `eth_sign` and `eth_sendTransaction` while it is unlocked.

| Client  | Method invocation                                                          |
| :------ | -------------------------------------------------------------------------- |
| Console | `personal.unlockAccount(address, passphrase, duration)`                    |
| RPC     | `{"method": "personal_unlockAccount", "params": [string, string, number]}` |

### Examples

```js
> personal.unlockAccount("0x5e97870f263700f46aa00d967821199b9bc5a120")
Unlock account 0x5e97870f263700f46aa00d967821199b9bc5a120
Passphrase:
true
```

Supplying the passphrase and unlock duration as arguments:

```js
> personal.unlockAccount("0x5e97870f263700f46aa00d967821199b9bc5a120", "foo", 30)
true
```

To type in the passphrase and still override the default unlock duration, pass `null` as the passphrase.

```js
> personal.unlockAccount("0x5e97870f263700f46aa00d967821199b9bc5a120", null, 30)
Unlock account 0x5e97870f263700f46aa00d967821199b9bc5a120
Passphrase:
true
```

## personal_unpair {#personal-unpair}

Deletes a pairing between wallet and Geth.

| Client  | Method invocation                                           |
| :------ | ----------------------------------------------------------- |
| Console | `personal.unpair(url, pin)`                                 |
| RPC     | `{"method": "personal_unpair", "params": [string, string]}` |

## personal_sendTransaction {#personal-sendtransaction}

Validate the given passphrase and submit transaction.

The transaction is the same argument as for `eth_sendTransaction` (i.e. [transaction object](/docs/interacting-with-geth/rpc/objects#transaction-call-object)) and contains the `from` address. If the passphrase can be used to decrypt the private key belogging to `tx.from` the transaction is verified, signed and send onto the network. The account is not unlocked globally in the node and cannot be used in other RPC calls.

| Client  | Method invocation                                                |
| :------ | ---------------------------------------------------------------- |
| Console | `personal.sendTransaction(tx, passphrase)`                       |
| RPC     | `{"method": "personal_sendTransaction", "params": [tx, string]}` |

### Examples

```js
> var tx = {from: "0x391694e7e0b0cce554cb130d723a9d27458f9298", to: "0xafa3f8684e54059998bc3a7b0d2b0da075154d66", value: web3.toWei(1.23, "ether")}
undefined
> personal.sendTransaction(tx, "passphrase")
0x8474441674cdd47b35b875fd1a530b800b51a5264b9975fb21129eeb8c18582f
```

## personal_sign {#personal-sign}

The sign method calculates an Ethereum specific signature with:
`sign(keccak256("\x19Ethereum Signed Message:\n" + len(message) + message))`.

By adding a prefix to the message makes the calculated signature recognisable as an Ethereum specific signature. This prevents misuse where a malicious DApp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.

See ecRecover to verify the signature.

| Client  | Method invocation                                                     |
| :------ | --------------------------------------------------------------------- |
| Console | `personal.sign(message, account, [password])`                         |
| RPC     | `{"method": "personal_sign", "params": [message, account, password]}` |

### Examples

```js
> personal.sign("0xdeadbeaf", "0x9b2055d370f73ec7d8a03e965129118dc8f5bf83", "")
"0xa3f20717a250c2b0b729b7e5becbff67fdaef7e0699da4de7ca5895b02a170a12d887fd3b17bfdce3481f10bea41f45ba9f709d39ce8325427b57afcfc994cee1b"
```

## personal_signTransaction {#personal-signtransaction}

SignTransaction will create a transaction from the given arguments and tries to sign it with the key associated with `tx.from`. If the given passwd isn't able to decrypt the key it fails. The transaction is returned in RLP-form, not broadcast to other nodes. The first argument is a [transaction object](/docs/interacting-with-geth/rpc/objects) and the second argument is the password, similar to `personal_sendTransaction`.

| Client  | Method invocation                                                |
| :------ | ---------------------------------------------------------------- |
| Console | `personal.signTransaction(tx, passphrase)`                       |
| RPC     | `{"method": "personal_signTransaction", "params": [tx, string]}` |

## personal_ecRecover {#personal-ecrecover}

`ecRecover` returns the address associated with the private key that was used to calculate the signature in `personal_sign`.

| Client  | Method invocation                                                  |
| :------ | ------------------------------------------------------------------ |
| Console | `personal.ecRecover(message, signature)`                           |
| RPC     | `{"method": "personal_ecRecover", "params": [message, signature]}` |

### Examples

```js
> personal.sign("0xdeadbeaf", "0x9b2055d370f73ec7d8a03e965129118dc8f5bf83", "")
"0xa3f20717a250c2b0b729b7e5becbff67fdaef7e0699da4de7ca5895b02a170a12d887fd3b17bfdce3481f10bea41f45ba9f709d39ce8325427b57afcfc994cee1b"
> personal.ecRecover("0xdeadbeaf", "0xa3f20717a250c2b0b729b7e5becbff67fdaef7e0699da4de7ca5895b02a170a12d887fd3b17bfdce3481f10bea41f45ba9f709d39ce8325427b57afcfc994cee1b")
"0x9b2055d370f73ec7d8a03e965129118dc8f5bf83"
