URL alias to access user profile as admin I realized that users on my site have their path ending in the form "user/number" (for example: user/3) when I check People in the Admin Toolbar and click on their username. I would like to use URL aliasing or some alternative that allows the path end with their username (for example: user/john_smith). How can I do this?
You can create aliases using the Pathauto module.


  The Pathauto module automatically generates URL/path aliases for
  various kinds of content (nodes, taxonomy terms, users) without
  requiring the user to manually specify the path alias. This allows you
  to have URL aliases like /category/my-node-title instead of /node/123.
  The aliases are based upon a "pattern" system that uses tokens which
  the administrator can change.


There are various tutorials of this module you can watch.
