Contour Connect is a free Android application developed by СКБ Контур under the Utilities & Tools category. It generates two-factor authentication codes to provide an additional layer of security to your account. With 2FA, you need to enter not only your password but also the code generated by the app to access your account. This means that even if someone gets hold of your password, they cannot access your information unless they have your phone.

Setting up 2FA with Contour Connect is easy. Just scan the QR code in the Kontur employee's office, and you're good to go. The app works with various other services, including Google, VKontakte, Mail.ru, GitHub, GitLab, and many others.

One of the best features of Contour Connect is that it allows you to confirm your login via a push notification that will be sent to your device. This is a convenient way of authenticating your login without having to enter the code manually. Another great feature is that you can use the app offline to confirm your login, as digital codes are generated automatically.

Overall, Contour Connect is an excellent choice for anyone looking to add an extra layer of security to their accounts. It is easy to use, works offline, and supports a wide range of services.
