Answer 1

You don't decrypt passwords with bcrypt because it's a one-way algorithm. What you can do is provide the plaintext and the hash (from the database) and compare.

Example:

const passwordEnteredByUser = "123456"
const hash = "HASH_STRING"

bcrypt.compare(passwordEnteredByUser, hash, function(err, isMatch) {
  if (err) {
    throw err
  } else if (!isMatch) {
    console.log("Password doesn't match!")
  } else {
    console.log("Password matches!")
  }
})
