Change my own settings
The User Settings pop-up window is located under the User menu → Settings. The User menu is located on the top-left side of the screen, showing the user name and the domain separated by @. (In the example underneath a@local is the name of the user menu. "a" is the user name and "local" is the domain.)
A simple pop-up window is activated where the main application language can be set as well as the Multifactor authentication mandatory status and a new QR-code can be generated (if the multifactor authentication is set to be required).
To apply changes simply click on the Save button.
