/**
 * This component is used to "protect" content that is not intended for public consumption yet, i.e. early access content.
 * 
 * For the moment this is completely insecure, as it relies on a single shared password for all users that is publicly
 * viewable. Additionally, the password can be easily bypassed.
 * 
 * However, this is fine for us as the content is not a secret or sensitive. We just want to prevent dissuade users from
 * using the content outside of the early adopter group, not completely prevent it.
