Going back to the information security section, you may remember that storing plaintext passwords is never okay. Now it is time to implement BCrypt to solve this issue.

bcrypt@~5.0.0 has already been added as a dependency, so require it in your server. You will need to handle hashing in 2 key areas: where you handle registering/saving a new account, and when you check to see that a password is correct on login.

Currently on your registration route, you insert a user's plaintext password into the database like so: password: req.body.password. Hash the passwords instead by adding the following before your database logic: const hash = bcrypt.hashSync(req.body.password, 12);, and replacing the req.body.password in the database saving with just password: hash.

On your authentication strategy, you check for the following in your code before completing the process: if (password !== user.password) return done(null, false);. After making the previous changes, now user.password is a hash. Before making a change to the existing code, notice how the statement is checking if the password is not equal then return non-authenticated. With this in mind, change that code to look as follows to properly check the password entered against the hash:

if (!bcrypt.compareSync(password, user.password)) { 
  return done(null, false);
}

That is all it takes to implement one of the most important security features when you have to store passwords.

--hints--

BCrypt should be a dependency.

async (getUserInput) => {
  const url = new URL("/_api/package.json", getUserInput("url"));
  const res = await fetch(url);
  const packJson = await res.json()
  assert.property(
    packJson.dependencies,
    'bcrypt',
    'Your project should list "bcrypt" as a dependency'
  );
}

BCrypt should be correctly required and implemented.

async (getUserInput) => {
  const url = new URL("/_api/server.js", getUserInput("url"));
  const res = await fetch(url);
  const data = await res.text();
  assert.match(
    data,
    /require.*("|')bcrypt\1/gi,
    'You should have required bcrypt'
  );
  assert.match(
    data,
    /bcrypt.hashSync/gi,
    'You should use hash the password in the registration'
  );
  assert.match(
    data,
    /bcrypt.compareSync/gi,
    'You should compare the password to the hash in your strategy'
  );
}
