+title: Rover config commands
+description: Create and manage configuration profiles
+---
+
+The Rover CLI enables you to create multiple **configuration profiles**, each of which corresponds to a different identity in Apollo Studio. Each configuration profile has an associated [API key](/studio/api-keys), which determines its permissions. You manage your configuration profiles with the `rover config` set of commands.
+
+## Displaying configuration profiles
+
+### `config list`
+
+The `config list` command lists all of your stored configuration profiles:
+
+```
+rover config list
+
+Profiles:
+
+default
+sso
+```
+
+### `config whoami`
+
+The `config whoami` command displays the details of your current active configuration profile:
+
+```
+rover config whoami
+
+Checking identity of your API key against the registry.
+Key Type: USER
+User ID: gh.StephenBarlow
+Origin: --profile default
+API Key: user************************************abcd
+```
+
+## Creating configuration profiles
+
+### `config auth`
+
+You create a new configuration profile with the `config auth` command:
+
+```
+rover config auth
+
+Go to https://studio.apollographql.com/user-settings and create a new Personal API Key.
+Copy the key and paste it into the prompt below.
+>
+```
+
+By default, your configuration profile is saved with the name `default`. You can specify a different name with the `--profile` option:
+
+```
+rover config auth --profile sso
+```
+
+## Deleting configuration profiles
+
+### `config delete`
+
+The `config delete` command deletes a single configuration profile, specified by its name:
+
+```
+rover config delete sso
+
+Successfully deleted profile "sso"
+```
+
+### `config clear`
+
+The `config clear` command deletes **all** of your stored configuration profiles:
+
+```
+rover config clear
+
+Successfully cleared all configuration.
+```

+title: The Rover explain command
+description: Understand Rover error codes
+---
+
+Usually when a Rover command results in an error, the command's output includes an error code:
+
+```sh {4}
+rover supergraph compose --config supergraph.yaml
+
+Composing supergraph with Federation v2.0.5.
+error[E029]: Encountered 1 build error while trying to build a supergraph.
+```
+
+The command above resulted in an error with code `E029`.
+
+You can use the `rover explain` command to output the description for a particular error code:
+
+```
+rover explain E029
+```
+
+Descriptions for _all_ Rover error codes are also available in [this article](../errors/).
