Extreme anonymity meets ephemeral messaging.
When considering a new messenger, there are a lot of questions you need to ask yourself. What are your friends and coworkers using? What platforms is it available on? What's your threat model? If you need an ephemeral messenger with strong crypto, Cyph might be for you.
Unlike more conventional messengers, Cyph runs in your browser. There's no stand-alone app, and Cyph doesn't require installation or registration. No usernames. You don't even have to give them a phone number or email address. You literally just go to Cyph's homepage and hit the "Start New Cyph" button. That's it. From there, a new private chat session starts and anyone with the unique URL can join. Despite being browser based, Cyph still supports handy features like video calling and file transfers. Cyph is also available as an onion service using Tor for additional anonymity.
Cyph isn't for everyone, but it's definitely a valuable tool for users who need extreme anonymity and ephemeral messaging.
SKILL LEVEL: INTERMEDIATE

SMS, Facebook Messenger, Snapchat, Google Hangouts, Skype, or Yahoo Messenger
Any modern browser, including Tor
While Cyph lacks a standalone app, it has some really interesting, valuable features for extreme anonymity.
Using Cyph is surprisingly easy to use and reliable in the tests I've run with users over the web and Tor.
Unfortunately, Cyph's visual aesthetic might be bad enough to keep some users from experimenting with it.
