Authenticator by KeepSolid is a utility app used with Facebook, Google, Amazon, and other apps to create an extra layer of two-factor (TFA or 2FA) protection when accessing your accounts. With this code generator, you can add a second validation challenge in addition to logins and passwords and protect your data from any unauthorized access. Multi-factor authentication with time-based one-time passwords (TOTP) guarantees access to your account for only verified parties whatever service you use, Facebook, Google, GitHub, Sony PlayStation, or Steam. This mobile app generates time-based one-time passwords that are more secure than event-based ones and widely used in creating security keys for multi-factor or two-factor authentication. WHAT IS TWO-FACTOR AUTHENTICATION (TFA) Two-factor authentication is a security method that requires two separate forms of identification to access your account: something you know (your password) and something you have (a special code from the TFA app on your trusted device). For instance, even if hackers get your password they will not be able to get access to your Binance or Amazon account as they will not have the secret code from Authenticator Mobile App. HOW THE AUTHENTICATOR APP WORKS When you activate the TFA in any service, you can add KeepSolid Authenticator as a second authentication factor. For example, after you add your Instagram or Facebook account to the Authenticator app, it will generate a time-based one-time password that you can use to confirm that it's you logging in to a website or service. BENEFITS OF MULTI-FACTOR AUTHENTICATION AND AUTHENTICATOR APP We use a myriad of online services every day: Instagram, Facebook, Amazon, Binance, etc. and each of them contains sensitive information that we need to protect. If you don’t want to become a victim of identity theft or data leakage, you need a verified authenticator app. Multi-device support. If you decide to use another device for two-factor authentication you don’t need to transfer each separate account manually. You will be able to create an archive file which you can save wherever you want and import your items on a new device. Secure 2FA protection. Using the verified KeepSolid Authenticator app to generate time-based one-time passwords is more secure than text messaging or email. The primary reason is that it's more difficult for a third party to gain physical access to your device and generate a code without you knowing about it. User-friendly navigation and interface. The Authenticator app by KeepSolid was designed with all users in mind. With our app, you don’t need special technical knowledge to activate the two-factor authentication (TFA) or use the time-based one-time passwords on any service you use. All the code generator interface elements are intuitive. All accounts in one place. With our TOTP code generator, you can link many accounts with TFA enabled and you will don’t need to register new emails to use Multi-factor authentication or TFA on new accounts. All your time-based one-time passwords will be kept in one place. The KeepSolid Authenticator app will provide you with an extra layer of security for your Microsoft Windows, Apple, Sony, or any other accounts. With multi-factor authentication and time-based one-time passwords, you don’t need to rely on a single password. With the rising number of identity thefts and cyber attacks in 2022, you have every reason to look for better ways to stay safe on the web. And The KeepSolid Authenticator App is the solution.
