 ### Static roles
 
-The database secrets engine supports the concept of "static roles", which are
-a 1-to-1 mapping of Vault Roles to usernames in a database. The current password
-for the database user is stored and automatically rotated by Vault on a
-configurable period of time. This is in contrast to dynamic secrets, where a
-unique username and password pair are generated with each credential request.
-When credentials are requested for the Role, Vault returns the current
-password for the configured database user, allowing anyone with the proper
-Vault policies to have access to the user account in the database.
-
--> Please consult the specific database documentation on the left navigation or
-the table below under [Database Capabilities](#database-capabilities) to see if
-a given database backend supports static roles.
+With dynamic secrets, Vault generates a unique username and password pair for
+each unique credential request. Vault also supports **static roles** for
+some database secrets engines. Static roles are a 1-to-1 mapping of Vault roles
+to usernames in a database. With static roles, Vault stores, and automatically
+rotates, passwords for the associated database user based on a configurable
+period of time.
+
+When a client requests credentials for the static role, Vault
+returns the current password for whichever database user is mapped to the
+requested role. With static roles, anyone with the proper Vault policies can
+access the associated user account in the database.
+
+<Warning title="Do not use static roles for root database credentials">
+   Do not manage the same root database credentials that you provide to Vault in
+   <tt>config/</tt> with static roles.
+
+   Vault does not distinguish between standard credentials and root credentials
+   when rotating passwords. If you assign your root credentials to a static
+   role, any dynamic or static users managed by that database configuration will
+   fail after rotation because the password for <tt>config/</tt> is no longer
+   valid.
+
+   If you need to rotate root credentials, use the
+   [Rotate root credentials](vault/api-docs/secret/database/index.mdx#rotate-root-credentials)
+   API endpoint.
+</Warning>
+
+Consult the [database capabilities table](#db-capabilities-table) to determine
+if your chosen database backend supports static roles.
