Streaming video apps like Google Play Music and Spotify are inherently a game of guesswork for password sharing. Without an official login, someone can use the default login and answer a friend’s questions or guess your passwords by viewing your stream. That’s why decentralized messaging app Jam has just launched with a key feature to preserve your unique viewing passwords.

Jam has always had a strong sense of community, whether that means creating its own emoji or just letting each you and your Jammers have your own keyboards. But it also launches an email address that sends you a link to a secure URL that allows you to type in your password while keeping them private.

Having your username protected made sense for Jam’s open platform. It has a lot of copyright-protected music, and the lack of options to change this would make it dangerous for people to store their super-secret listening parties and chats on the app. Instead, Jam lets people share what you’re listening to and it’s easy to find the exact music.

Getting this feature right is crucial for upstarts to get the zeitgeist. Showtime could have lots of LiveEvents to broadcast, but would be a better candidate for streaming chat rooms instead of drawing attention to its poorly organized app by giving away too many secret passwords. This could give the app a spike in its usage, or even jumpstart a monetization strategy for its $5 million in funding.
