getpasswd functionality in Go?

Question

Situation:

I want to get a password entry from the stdin console - without echoing what the user types. Is there something comparable to getpasswd functionality in Go?

What I tried:

I tried using syscall.Read, but it echoes what is typed.

The following is one of best ways to get it done. First get terminal package by go get golang.org/x/crypto/ssh

package main

import (
    "bufio"
    "fmt"
    "os"
    "strings"
    "syscall"

    "golang.org/x/crypto/ssh/terminal"
)

func main() {
    username, password, _ := credentials()
    fmt.Printf("Username: %s, Password: %s\n", username, password)
}

func credentials() (string, string, error) {
    reader := bufio.NewReader(os.Stdin)

    fmt.Print("Enter Username: ")
    username, err := reader.ReadString('\n')
    if err != nil {
        return "", "", err
    }

    fmt.Print("Enter Password: ")
    bytePassword, err := terminal.ReadPassword(int(syscall.Stdin))
    if err != nil {
        return "", "", err
    }

    password := string(bytePassword)
    return strings.TrimSpace(username), strings.TrimSpace(password), nil
}
