Unfortunately in Matomo a user cannot edit their usernames. However there is an easy solution.

Follow these steps to create a new user with the correct username:

  • Login as Super User in Matomo, or ask a Super User to follow these steps for you.
  • Go to Administration​ ​​> Users.
  • Change the email address for your current user (the one with the wrong username). For example change it to “example@example.com”.
  • Create a new user with the right username.
  • Assign this new user the same permissions as the old user.
  • Save the changes.
  • Then delete the old user.

    Now you can use the new user with the correct username!
