How to convert type in golang?

I need to hid a password. I get (mismatched types []byte and int). How can i fix it? How can I convert from int to []byte?

package main

import ("fmt"; "github.com/howeyc/gopass")

func main() {
    var user string
    maping := map[string]int{"dasha": 123, "mike": 777}

    fmt.Println("Enter username: ")
    fmt.Scan(&user)
    fmt.Printf("Enter password: ")
    pass, err := gopass.GetPasswd()
    if err != nil {
        return
    }
    if pass == maping[user] {
        fmt.Println("bingo")
    }else{
        fmt.Println("the login or password is not correct")
    }
}

You can do the conversion with strconv's Atoi() function:

i, err := strconv.Atoi("-42")

And you'd convert your []byte to a string with

s := string(byteArray[:])

So the combination is 

i, err := strconv.Atoi(string(pass[:]))
