Daniel: In Directus 10.11, we introduced public user registration. This allows for users to register new accounts directly from the login screen or via the API. Let me show you how it works. Once enabled in your project settings, users will see a link on the sign in screen. They click it, register, and can immediately log in.
You can also enable email verification, and they and they won't be able to log in. You can also set up rules that the email address must match. This is more powerful than just enabling email allow listing as you can set more complex rules based on your needs. And then in Directus 10.12, we applied feedback about this feature and created a set of environment variables to control how many users can exist in your project. Before now, you had to use a series of perfectly configured settings to enable public registration in a separate application or custom extensions.
We're always looking to apply your feedback to directors. We hope this feature makes your development easier.
