This repository is a simple example of how to use Remix Auth TOTP on Cloudflare.

• Clone the repository and install its dependencies:

pnpm install

• Get required .dev.vars environment variables for Cloudflare:

This example uses Resend to send emails. You can create a free account and get your API key here. Or you can leave RESEND_API_KEY blank and the example will simulate sending emails.

Note Remember to replace the current .dev.vars.example file with your own .dev.vars file.

• Run local D1 migrations:

pnpm run d1:migrate:apply

• Run the server:

pnpm run dev

And you're ready to go! 🎉

• Console spits out 302's continuously. This may occur after rebuilding local from scratch, especially the database, and there are stale cookies in the browser. Clearing cookies for the application in the browser should fix.
