What is 2FA?​

2FA is a way of granting access to users only after presenting two separate pieces of evidence (factors). One of these factors is usually a password which the user should know and the other factor something they have or even something they are. This way you can be sure that only knowing your password won't be enough for an attacker to gain access to your account.

How does 2FA work in ConfigCat?​

In our case the first factor is password you use to login to ConfigCat Dashboard. The second factor is a 6-digit number generated via an Authenticator App.

"Thank you guys, you rock."​

We love to get emails like the one above. And sometimes we do. 😃 Actually, more often than I've ever dared to imagine.

Part of the reason our users love us (well, when they do) are those million little tweaks we do to our feature flag service on a daily basis.

Normally we don't share those little tweaks and updates

Our architecture, stacks and why did we choose them. A recipe for SaaS startups for an affordable, scalable and high-performing system that scales well.

ConfigCat is using ConfigCat as a feature flag and configuration management service. Here is how and why.​

In this post, I will show you how we implemented the animations where the cat follows the cursor with his eyes when entering username and hides them when entering password.

We are very excited about the release of our new shiny Landing Page on configcat.com.

Use Feature Flags, and you do not need to worry about the ambiguous Apple App Store review. Also, you can forget about the release trains or the good old days when PMs are running around in the office with flame-throwers.

Let me tell you a story about the myth of the Friday Release. Newbie QA guy was finishing up his tasks on a Friday evening after hours. The office was quite empty at that time, only a few people left.
