One account for every Collared app. It knows where your data lives, never what it says.
How people find you. Letters, digits, - and _.
For sign-in links. Nobody else sees it unless you allow an app to.
Relationships you start are hosted there. You can still join one hosted elsewhere.
At least 10 characters. Or skip it: next you can add a passkey, and a sign-in link by email always works.
Are you sure?
