Single User Project

Hello all. I have a general question. I have created a simple photon project that I would like to give someone as a gift. The project uses a website to send commands to the photon. I am wondering how necessary it is to generate an Oauth token for communication. Currently I am not hosting the .html publicly, but may migrate it in the future. The repercussions of the public website being discovered by someone else are not exceptionally grave, more annoying. It seems from forum posts that maybe Oauth is used more on a larger scale product level, but maybe I am misinterpreting things. Also, I swear I saw a cost associated with it somewhere in this forum, but I cannot find it to reference. Is use of Oauth through particle free? Thanks.
