 As a reminder, this project is being built upon the following starter project on <a href='https://glitch.com/edit/#!/remix/clone-from-repo?REPO_URL=https://github.com/freeCodeCamp/boilerplate-advancednode/'>Glitch</a>, or cloned from <a href='https://github.com/freeCodeCamp/boilerplate-advancednode/'>GitHub</a>.
 Going back to the information security section you may remember that storing plaintext passwords is <em>never</em> okay. Now it is time to implement BCrypt to solve this issue.
 <hr>Add BCrypt as a dependency and 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 our registeration route, you insert a user's password into the database like the following: <code>password: req.body.password</code>. An easy way to implement saving a hash instead is to add the following before your database logic <code>var hash = bcrypt.hashSync(req.body.password, 12);</code> and replacing the <code>req.body.password</code> in the database saving with just <code>password: hash</code>.

 Finally on our authentication strategy we check for the following in our code before completing the process: <code>if (password !== user.password) { return done(null, false); }</code>. After making the previous changes, now <code>user.password</code> 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 your code could look as follows to properly check the password entered against the hash: <code>if (!bcrypt.compareSync(password, user.password)) { return done(null, false); }</code>
 That is all it takes to implement one of the most important security features when you have to store passwords! Submit your page when you think you've got it right.
