Move the endpoint and migration step out of the custom provider branch, where a reader following the Serverpod Cloud path would never see it, and fold the parameter list back into the section it documents. Split the dense Cloud delivery paragraphs and drop the appDisplayName length limit, which the API already enforces.
The page read as if ServerpodCloudEmailIdpConfig pointed at a transactional email service that any server could use. It does not: the delivery is part of the Serverpod Cloud platform, and the key it authenticates with is injected into the deployed instance and is not obtainable anywhere else. Say so where a self-hosted reader would otherwise pick the wrong configuration and find out in production.
Cut the explanation block that had grown at the top of the page and the one under Server-side configuration. The generated configuration is now the single path through the page, followed by the endpoint and migration step, with the Cloud-only scope and the delivery failure behavior as short hooks where a reader runs into them. Move the custom provider to a variant section at the end, and leave the Cloud passwords page alone.

| Then extend the abstract endpoint to expose the email authentication routes on the server. Create the file anywhere under your server's `lib/` directory (for example, `<project>_server/lib/src/endpoints/`); the generator picks it up: | ||

| ```dart | ||
| import 'package:serverpod_auth_idp_server/providers/email.dart'; | ||
|
|
||
| class EmailIdpEndpoint extends EmailIdpBaseEndpoint {} | ||
| ``` | ||
|
|
||
| Then, start the server with `serverpod start` to generate the client code, then create and apply the migration that initializes the database for the provider (in the `serverpod start` terminal, press **M**, then **A**). More detailed instructions can be found in the general [identity providers setup section](../../setup#identity-providers-configuration). |

Suggestion: The endpoint and migration steps are already done in newly generated projects: serverpod create runs with auth enabled, scaffolds lib/src/auth/email_idp_endpoint.dart with the EmailIdpBaseEndpoint extension, and creates the initial migration. As written, a new-project reader who was just told "Newly generated projects already configure the email identity provider" is then instructed to create a file they already have. Suggest scoping these steps the same way, e.g.: "Newly generated projects already include this endpoint at lib/src/auth/email_idp_endpoint.dart. If you are adding the auth module to an existing project, extend the abstract endpoint and create and apply the migration yourself:".
| Set `appDisplayName` to the name recipients should see in the verification emails. In the `development` and `test` run modes the codes are written to the server log instead of being sent, so you can complete the flow locally.

| `ServerpodCloudEmailIdpConfig` sends email only for apps running on Serverpod Cloud, which injects the key it authenticates with on deploy. If you host the server yourself, switch to [your own email provider](#use-your-own-email-provider) before you go to staging or production. |

Question: The PR description mentions adding a paragraph to the Cloud passwords page describing scloudAuthEmailKey, linked from here, but the diff only touches the setup page and the key is never named in it. The info box's "the key it authenticates with" is left dangling as a result. Was the passwords-page paragraph dropped deliberately, or did that change not make it into the push?

| Serverpod Cloud delivery is there to get sign-in working quickly, and it sends a standard message carrying your `appDisplayName`. You might prefer using a custom email provider to have full control over the body, layout, and language of the emails. For servers hosted outside of Serverpod Cloud, it is the only option. | ||
|
|
||
| Changing the email provider is done by replacing `ServerpodCloudEmailIdpConfig` with `EmailIdpConfig`, which requires you to pass your own callbacks for the two codes. One convenient option is the [mailer](https://pub.dev/packages/mailer) package, which can send emails through any SMTP service. Most email providers, such as Resend, Sendgrid or Mandrill, support SMTP. |

Question: The PR description says the custom path stays on EmailIdpConfigFromPasswords, but the example uses EmailIdpConfig with secretHashPepper: pod.getPassword('emailSecretHashPepper')!. The class docs on ServerpodCloudEmailIdpConfig point custom-provider users to EmailIdpConfigFromPasswords, which reads the same pepper itself and shortens the example to the two callbacks. Which one is intended here? If EmailIdpConfigFromPasswords, the Basic configuration options list needs a matching pass, since it documents secretHashPepper as required.

Suggestion: Sending is keyed to the run mode, not to where the app runs (the source switches on staging/production, and the PR description says the same). A self-hosted server in production run mode doesn't log the codes; it attempts to send and the failure is only logged.

| To properly configure Sign in with Email, you must connect your Serverpod to an external service that can send the emails. One convenient option is the [mailer](https://pub.dev/packages/mailer) package, which can send emails through any SMTP service. Most email providers, such as Resend, Sendgrid or Mandrill, support SMTP. | ||
| Sign in with Email verifies the user's address with a code, both when they register and when they reset their password. |

Suggestion: The frontmatter description still says "Connect Serverpod to an SMTP service and configure the email identity provider", which now contradicts this intro, since the default needs no SMTP service. Something like: "Sign in with Email lets users authenticate with an email and password. Email delivery works out of the box on Serverpod Cloud, or through your own provider."
