+ozone tenant user getsecret <ACCESS_ID>
+```
+
+Example:
+
+```shell
+bash-4.2$ ozone tenant user get-secret 'tenantone$testuser'
+export AWS_ACCESS_KEY_ID='tenantone$testuser'
+export AWS_SECRET_ACCESS_KEY='<GENERATED_SECRET>'
+```
+
+### Set tenant user secret key

+
+Secret key length should be at least 8 characters.

+or
+
+```shell
+ozone tenant user setsecret <ACCESS_ID> --secret <SECRET_KEY>
