# 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. <br><br> MetaMask implements `personal_sign` similarly to the Go Ethereum client's `eth_sign` implementation. MetaMask's `personal_sign` doesn't accept a password. <br><br> 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.
