Make it so a user needs to input a code before signing up for each event.

Right now, our portal allows anyone to be able to sign up for an event to be checked off when in reality they may have never been to the event at all. To mitigate this, we can allow officers to set a special code for each event that inductees need to type into the event portal before they have the ability to sign in and check themselves off. The assignee has the freedom to implement this however they see fit as long as it's intuitive on the UI. This involves both frontend modifications and backend updates as well (storing codes per event on the db and fetching them appropriately).
