Introduction to Operation Super Ship

In this article, we will explore Operation Super Ship, a project aimed at creating a login system that allows users to sign up with a username instead of or with an email address. We will dive into the process of implementing this feature, step by step, using the Super Base authentication system.

How to Sign Up with a Username

One of the main goals of Operation Super Ship is to provide users with an alternative way to sign up for an account on a website without the need for an email address or any other identifying information. This feature appeals to those who value the privacy and freedom associated with the wild west mentality of the internet.

To get started, we need to add a new table to our public scheme called "usernames". This table will serve as a reference for storing usernames associated with user IDs. We will create a foreign key to link the "usernames" table to the "users" table of the auth schema.

Creating a Usernames Table

The next step in implementing the username sign up feature is to create the "usernames" table. This table will store the usernames provided by the users during the sign-up process. We can add a unique constraint to the "username" column to ensure that each username is unique.

Adding RLS Policy for Sign Up

To ensure that only the logged-in user can create a row for themselves in the "usernames" table during the sign-up process, we need to add a Row-Level Security (RLS) policy. This policy will restrict access to the table and allow only the user who is currently logged in to create a row.

Configuring Email Settings

In order to finalize the configuration for the new login with a username hack, we need to make some adjustments to the existing email settings. We need to go to the auth providers in the Super Base dashboard and disable the confirm email and secure email change options.

Implementing the Username Login Hack

Now that all the necessary configurations have been set up in Super Base, we can move on to implementing the username login hack on the front end of our application. This involves creating a sign-up form where users can enter their desired username and password. We have provided some quick functionality and templating to assist in creating this form.

Logging in with Username and Password

After the user has created their account using a username and password, the next challenge is allowing them to log back in. This requires retrieving the email associated with the username so that it can be used along with the password to log in. We will utilize the Super Base client, logged in with a service role key, to retrieve the email from the username.

Getting the Email from the Username

To get the email from the username, we will create a Super Base function called "get_fake_email". This function will take the username as input and use the Super Base client, logged in with a service role key, to retrieve the associated email from the "usernames" table. Once the email is obtained, it can be used along with the password for the login process.

Using the Superbase Service Role Key

It is important to note that the Super Base service role key should never be exposed in the front-end application. This key gives administrative access to the database and should be kept confidential. Care should be taken to safeguard this key to maintain control over the database.

Conclusion

In conclusion, the Super Base username login hack provides an alternative way for users to sign up and log in to websites without the need for an email address. While this feature may not be suitable for production environments due to potential security issues and limitations, it serves as an interesting exploration of the capabilities of the Super Base authentication system. By following the steps outlined in this article, you can experiment with implementing this feature in your own projects.
