> **Note:** If you want to retain ownership over the original namespace and
protect the URL redirects, then instead of changing your username, you can
create a new group and transfer projects to it.
Alternatively, you can follow [this detailed procedure from the GitLab Team Handbook](https://about.gitlab.com/handbook/tools-and-tips/#how-to-change-your-username-at-gitlabcom).
Changing your username can have unintended side effects.
* Existing web URLs for the user and anything under it (i.e. projects) will
redirect to the new URLs
* Existing Git remote URLs for projects under the user will no longer work, but
Git responses will show an error with the new remote URL
* The original namespace can be claimed again by any group or user, which will
destroy any web redirects and Git remote warnings
> It is currently not possible to rename a namespace if it contains a
project with container registry tags, because the project cannot be moved.
