Also called 2FA (two-factor authentication), this function adds a second confirmation of the user's identity during login, preventing access to accounts even if the password has been compromised. The main purpose of this authentication is to make it more difficult to gain unauthorized access to the account. Even if the password is hacked or the phone stolen, it is unlikely that another user will be able to access your accounts, as they won't have the second verification factor. This feature is well known and used in some systems such as Gmail, Instagram, Facebook, Whatsapp and others. ** Do you have any recommended TWO-FACTOR AUTHENTICATION apps? ** We recommend the **Google Authenticator** or **Microsoft Authenticator** app, although there are several apps that can be used for login authentication. ![](https://storage.crisp.chat/users/helpdesk/website/9040e83e46dad000/image_ep803w.png) ![](https://storage.crisp.chat/users/helpdesk/website/9040e83e46dad000/image_ym0isn.png) __These apps are free and available for Android and iOS in the official Play Store and Apple Store.__ More information about the apps can be found at the links below: **Android ** ** - Google Authenticator - https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2&hl=pt_BR - Microsoft Authenticator - https://play.google.com/store/apps/details?id=com.azure.authenticator&hl=pt_BR **iOS ** - Google Authenticator - https://apps.apple.com/br/app/google-authenticator/id388497605 - Microsoft Authenticator - https://apps.apple.com/br/app/microsoft-authenticator/id983156458 --- ### How to enable Two-Factor Authentication? __Configuring Google Authenticator__ ${color}[#ff7b00](** 1 -** ) Log in to our platform ${color}[#ff7b00]( ** 2 -** ) At the top right click on your profile picture > Profile option, then go to the security tab > Enable Two-Factor Authentication ${color}[#ff7b00]( ** 3 -** ) Open Google Authenticator. ${color}[#ff7b00]( ** 4 -** )Tap the “+” button in the bottom right corner. ${color}[#ff7b00]( ** 5 -** ) Select “Scan QR code”.
