In my case I generate unique links to participants that are sent via email.
In this case I cannot use session to store them, as the user clicks the
links without registering to a website and can take several days before
registering.
I had an option to either pass all parameters in the link args, which would
make a long link, or to generate a unique code and store the parameters in
a table. I decided to do the latter for keeping the link short and for
security reasons (parameters would imply how to change link parameters
manually).
If the user does the tasks while signed in, I still generate the links the
same way, even though I could do it using the session, because I want to
avoid extra work :)
