Lukas here, founder of Changefly. For those of you who might remember neworder.box.sk and astalavista.box.sk, I was one of the admin's at a very young age. Fast forward to 2018, I set out to help people regain their privacy. Google invited us into the Google Cloud Startup program which led to the creation of Changefly.

After years of truly challenging work and thousands of iterations, Changefly ID was born. Changefly ID solves the problem both users and companies face on a daily basis... spam, scams, bots, account takeover attacks. At face value it looks like an ordinary code, but in fact, it is an encrypted security code that only the user knows and has access to use (a distributed anonymous authentication code).

Changefly ID has a lot of flexibility -- replace traditional authentication (which you absolutely should do) or use secondary for multi-factor authentication (a good stepping-stone). It also includes end-to-end communications with your users through Changefly (not email, sms, or other unsecured channels). Additionally, the Changefly app data is also end-to-end encrypted as is the local data. We made access to Changefly ID easy and free with our Developer API. Changefly ID really does stop bots, spam, scams, and other threats from getting anywhere near users or their accounts.

p.s. A big thanks to Tom (HN moderator) for their help!
