By default, Backend is accessible via /admin/ location appended to the main URL of your Magento store.
Due to recent vulnerabilities, brutesforce attacks and excessive load that may be put on default admin location at /admin/ it is strongly recommended to change default /admin/ path to something unique and verify that it is well hidden and patched with our Magento scan tool.
