+# Microsoft365 authentication
+
+By default Prowler uses MsGraph Python SDK identity package authentication methods using the class `ClientSecretCredential`.
+This allows Prowler to authenticate against microsoft365 using the following methods:
+
+- Service principal authentication by environment variables (Enterprise Application)
+- Current CLI credentials stored
+- Interactive browser authentication
+
+To launch the tool first you need to specify which method is used through the following flags:
+
+```console
+# To use service principal authentication
+prowler microsoft365 --sp-env-auth
+
+# To use cli authentication
+prowler microsoft365 --az-cli-auth
+
+# To use browser authentication
+prowler microsoft365 --browser-auth --tenant-id "XXXXXXXX"
+```
+
+To use Prowler you need to set up also the permissions required to access your resources in your Microsoft365 account, to more details refer to [Requirements](../../getting-started/requirements.md)
