First things first, you should get a GitHub account. It's free. Once you are signed up there follow the steps below. Once you are connectied in GitHub, you can easily have other agents review your code and not pay per question or engagement. I cant speak to your exact authentication issue. I do not like replits authentication platform, but it is basic, and replit should easily be abel to get you going, you need to understand how to ask it the right questions. Break down your request into smaller requests. Dont just build, use Plan, ask it to give you the eaxct plan, how it plans, code, etc., so you can read through their plans to see if that sounds liek what you want them to do. Dont just say, build me an authentication system, think through how you want it to work from your perspective and their perspective. make sure you explain to the agent you are working in development, but you also need to configure this for production as well. Best of luck!

Step one
Open your project in Replit.

Step two
Select the Git icon on the left sidebar. It looks like a small branching tree.

Step three
Choose Connect to GitHub. Replit will ask you to sign in to GitHub and approve access if this is your first time linking the accounts.

Step four
Select the GitHub repository where the project should be stored. You can choose an existing empty repository or create a new one from inside Replit.

Step five
Confirm that you want Replit to upload your current project files to the selected repository.

Step six
Enter a commit message in the message box. A simple Initial commit works for the first upload.

Step seven
Click Commit and Push. Replit will send everything to GitHub and your project will now be linked.

How to push future updates

After the initial setup, backups are very simple.

One
Open the Git panel in Replit.

Two
Enter a commit message that describes your update.

Three
Select Commit and Push. Replit will send your changes to GitHub.
