 ## Why don't I see my domain when I sign in to the registrar?
-If you had a .gov account prior to November 2023, **you can’t use your old credentials to access the new registrar**. You’ll need to [create a Login.gov account](https://login.gov/help/get-started/create-your-account/){.usa-link--external} with the same email address you used to sign in to the old registrar. That will ensure that you have access to your domains.
+Your domains are closely tied to the email address you use when signing in to the .gov registrar.
+
+**If you had a .gov account prior to November 2023**:  We launched a new .gov registrar. When signing in, you need to use a [Login.gov account](https://login.gov/help/get-started/create-your-account/){.usa-link--external} that’s associated with the same email address you used to sign in to the old registrar. That will ensure you have access to your existing domains. 
+
+**If you have more than one Login.gov account, or have more than one email address associated with your Login.gov account**: When signing in to the .gov registrar, you need to use the [Login.gov account](https://login.gov/help/get-started/create-your-account/){.usa-link--external} that’s associated with the email address your .gov domains are assigned to. 
+- If you have more than one Login.gov account, try [signing in](https://manage.get.gov/){target="_blank"}  with each account.
+- If you have more than one email address associated with your Login.gov account, try [signing in](https://manage.get.gov/){target="_blank"}  with a different email address. 
+- We recommend using a Login.gov account that is only linked to your work email.
+
+**If someone invited you to manage a domain**: Confirm which email address your domain invitation was sent to. When signing in to the .gov registrar, you need to use a [Login.gov account](https://login.gov/help/get-started/create-your-account/){.usa-link--external} that’s associated with the same email address that was invited. You may need to ask the person who sent the invitation to send another one to your preferred email address.

+If you’ve tried the above recommendations and still don’t see your domains, email us at <help@get.gov>.
