If your data has a home of its own, apps need a way to know it’s yours—and whether you’ve invited them in. That’s what auth is for.

​
Signing in and connecting an app

Your Basic account is your identity across apps built with Basic. You can use the same account rather than starting from scratch in each app. There are two separate choices:
  • Signing in confirms which account is yours.
  • Approving an app lets it work with the data it’s allowed to use.
Signing in alone doesn’t open your whole PDS to an app. A notes app can work with your notes without getting access to unrelated information.

​
You can change your mind

You can disconnect an app when you no longer want it to have access. The data it saved in your PDS stays there. This separates your account from any one app. You aren’t handing over your data’s home every time you try a new tool—you’re choosing who can use it.
