# personal_sign

Presents a plain text signature challenge to the user and returns the signed response. Prepends a safe prefix to the signed message to prevent the challenge tricking users into signing a financial transaction.  MetaMask implements `personal_sign` similarly to the Go Ethereum client's `eth_sign` implementation. MetaMask's `personal_sign` doesn't accept a password.  This method requires that the user has granted permission to interact with their account first, so make sure to call `eth_requestAccounts` (recommended) or `wallet_requestPermissions` first.

### Parameters

`Challenge`(string)required

A hex-encoded UTF-8 string to present to the user. See how to encode a string like this in the [browser-string-hexer](https://github.com/danfinlay/browser-string-hexer) module.

`Address`(string)required

The address of the requested signing account.

### Returns

A hex-encoded signature.
