Authentication Providers

A new auth provider can be added with the addition of a plugin with a koa router as the default export in /server/auth/[provider].ts and (optionally) a matching logo in /client/Icon.tsx that will appear on the sign-in button.

Auth providers generally use Passport strategies, although they can use any custom logic if needed. See the google auth provider for the cleanest example of what is required – some rules:

• The strategy name must be lowercase
• The strategy must call the accountProvisioner command in the verify callback
• The auth file must export a config object with name and enabled keys
• The auth file must have a default export with a koa-router
