getpasswd functionality in Go?

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

package main

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

    "golang.org/x/term"
)

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 := term.ReadPassword(int(syscall.Stdin))
    if err != nil {
        return "", "", err
    }

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