Key Provider

This key provider model allows us to have full control on the way unique codes are generated in Feedback Server. Functions like save / resume progress or answers changes requires to generate unique ids in order to allow the respondent to restore his session in a secure way.

By default Feedback Server is generating a unique code that will be delivered to the respondent if he choose for example to save his progress during a survey. But what happens if we have invited the respondent using an email invitation that has already a unique code for each email or the respondent has already received a token ?

That's were the key provider model comes in, it will allow us to specify which security addin will take the responsability to provide and manage the unique keys required to restore the respondent sessions and answers.

Following security addin can act as a key provider for a survey :

Coming back to our email invitation example, if we want to allow the respondent to resume a session later on using the same code than the one that is used by email code protection we could set the email code protection security addin to act as a key provider and the respondent will have only one code to use for all action related to his session.

Some providers like the Active Directory Security goes even a bit further as they automatically detect if an Active Directory user has saved a session and will resume it without having the user to enter any code.
