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.
