With MFA, a user may be required to enter an additional code in addition to the login requirements of a username and password. The code can be generated with the authenticator apps from Google or Microsoft
In the applications there is the possibility of impersonation.
This means that another user can be taken over from the app and web app with a few clicks.
You can set this option by editing "Configure managed users".
Other users can be linked to a specific user, such as a manager by means of set rights, which he/she may temporarily take over. This will then receive a function button "Accept user" in the app under "settings".
Pressing this function displays a list of users (based on set rights) that can be taken over. From the moment a user is taken over, all actions are performed by the replacement user.
After the execution of relevant tasks, you can switch back to your own account.
