With the default Magento 2 setup, reindexing requires running CLI commands. However, with the Magento 2 Backend Reindex from Admin Panel Extension, the process becomes straightforward:

• Log in to your Magento 2 Admin Panel.
• Navigate to System → Index Management.
• Select the indexes you want to reindex.
• Click the Reindex button directly from the grid.
• The extension processes the reindex instantly and confirms completion.

This eliminates the need for server access entirely, making Magento 2 reindex from admin panel accessible to any store owner regardless of technical skill level.
