+Tools that use {azure-short} services should always have restricted permissions to make sure that {azure-short} resources are safe. Therefore, instead of having applications sign in as a fully privileged user, {azure-short} offers service principals. An {azure-short} service principal is a name that can be used with applications, hosted services, or automated tools.
+
+This identity is used for access to resources.
 
+* Create a service principal
+* Sign in using a service principal and password
+* Sign in using a service principal and certificate
+* Manage service principal roles
+* Create an {azure-short} resource using a service principal
+* Reset service principal credentials
+
+For more details, see link:https://learn.microsoft.com/en-us/cli/azure/azure-cli-sp-tutorial-1?tabs=bash[Create an {azure-short} service principal with Azure CLI].
