* Add a flyout menu called `Access`. Use existing functionality already available in GitLab (for example `Security` sidebar menu in the homepage)
* Move the following pages (urls attached and preserved) under this flyout menu:
* [Password & authentication](https://gitlab.com/-/profile/two_factor_auth)
* [Personal access tokens](https://gitlab.com/-/user_settings/personal_access_tokens)
* [SSH keys](https://gitlab.com/-/user_settings/ssh_keys)
* [GPG keys](https://gitlab.com/-/user_settings/gpg_keys)
* [Applications](https://gitlab.com/-/user_settings/applications)
* [Active sessions](https://gitlab.com/-/user_settings/active_sessions)
* [Authentication log](https://gitlab.com/-/user_settings/authentication_log)
* Remove "Manage authentication" as an entry point from [Account](https://gitlab.com/-/profile/account) page
