 # Sub-Organization Email Auth
 
 Email auth is a powerful feature to couple with [sub-organizations](../getting-started/Sub-Organizations.md) for your users. This approach empowers your users to authenticate their Turnkey in a simple way (via email!), while minimizing your involvement: we engineered this feature to ensure your organization is unable to take over sub-organizations even if it wanted to.

 ## Pre-requisites
 
 Make sure you have set up your primary Turnkey organization with at least one API user that can programmatically initiate email auth. Check out our [Quickstart guide](../getting-started/Quickstart.md) if you need help getting started. To allow an API user to initiate email auth, you'll need the following policy in your main organization:
+
 ```json JSON
-{ 
-    "effect": "EFFECT_ALLOW",
-    "consensus": "approvers.any(user, user.id == '<YOUR_API_USER_ID>')",
-    "condition": "activity.resource == 'AUTH' && activity.action == 'CREATE'"

 }
 ```
 
 ## Helper packages
 
-* We have released open-source code to create target encryption keys, decrypt auth credentials, and sign Turnkey activities. We've deployed this a static HTML page hosted on `auth.turnkey.com` meant to be embedded as an iframe element (see the code [here](https://github.com/tkhq/frames)). This ensures the auth credentials are encrypted to keys that your organization doesn't have access to (because they live in the iframe, on a separate domain)
-* We have also built a package to help you insert this iframe and interact with it in the context of email auth: [`@turnkey/iframe-stamper`](https://www.npmjs.com/package/@turnkey/iframe-stamper)

 Congrats! You've succcessfully performed Email Auth! 🥳
+
+## Integration notes
+
+Before stamping an activity, if you'd like to validate whether or not an injected credential is still valid, you can use the `whoami` endpoint:
+
+```js
+const whoamiResponse = await client.getWhoami({
+  organizationId,
+});
+```
+
+A valid response indicates the credential is still live; otherwise, an error including `unable to authenticate: api key expired` will be thrown.
