+## Accessing your account
+
+To login to dbt Cloud, use the URL that applies to your environment.  Your access URL used will depend on a few factors including location and tenancy:
+- **US multi-tenant:** Use your unique URL that starts with your account prefix, followed by `us1.dbt.com`. For example, `abc123.us1.dbt.com`. You can also use `cloud.getdbt.com`, but this URL will be deprecated in the future. 
+    - If you are unsure of your access URL, navigate to `us1.dbt.com` and enter your credentials. If you are a member of a single account, you will be logged in and your URL will be displayed in the browser. If you are a member of muliple accounts, you will be presented with a list of options, along with the appropriate login URLs for each.
