The possibility to set a passwort (identification) on an "open for public" survey.
With this function it would be possible to get input from a larger but defined group of participants, without open the query/ questionaire to the public or get a full account for every person. The passwort protection should only allow the access to the survey. For accessing the data, there ist still the need of an account.
A typical usecase would be an survey (arcgis online), which ist sent to the every empolyee of my companie. For exampel to get the information about their daily way to work (Adress, transportation (public, car, bike etc.), travel time, etc.). 95% of the employee don't work with GIS and have no Account. I just need the input for this specific case. Therefore it is not possible/ nessecary to create an accout for everybody. With a passwort protection the risk of an access form outside of the company will be minimized.
There are different reasons why the questions of the survey should not be open for public.
e.g. minimize risk of inputs from outside of the defined group, protect the questions of the survey
The workaround to create a passkey-field which only allows one specific number (field limitations max and min) is not safe, due to the possibility to look up the limitations with help of the developer console of the browser.
