We have enabled 2-Factor Authentication on this site, which can be activated through your Settings page.
To get there, just click on your Profile Name -> Settings -> Security.
From here you can activate your 2FA, which will then require you to scan the QR code and enter the generated code on the app to confirm. After that, you will be given 5 recovery codes, you can save them somewhere and confirm. That’s it, now you have 2FA enabled! The next time you try to log in, you will be asked to enter your 2FA code.
Two-Factor Authentication (2FA) provides an extra layer of security to your account. Once enabled, in addition to your password, you’ll be required to enter a token from your authentication app when logging in or carrying out certain other actions. This ensures your account remains secure, even if your password is compromised, as attackers would also need a code (which changes every 30 seconds) to access your account.
Apps such as Google Authenticator, Authy, Microsoft Authenticator, and more are available for free.
