Google Authenticator

Google Authenticator is a two-step authentication (2FA) tool that provides time-based one-time password (TOTP) generation for protecting the apps and other services on your device. It offers an extra layer of security, as you have entered a six-digit code generated by Google Authenticator along with the password you are using. 

The innovative tool offers the best services, especially when you are using a public Wi-Fi or a friend’s handheld. You can use the app, even if you don’t have Wi-Fi access or cellular data. It is cross-platform, so you can use it for Windows, tablets, laptops, Android, and iOS devices as well.

What is Google Authenticator?

Google Authenticator is an official software-based authenticator that is developed by Google to offer multi-factor authentication services while using TOTP and HOTP. It is the best solution for users seeking extra security for their sensitive data, as it generates a six to eight-digit code, and you need to enter it along with your usual login details.

The cross-platform utility is a straightforward and offline-capable tool that works even when you are offline. You can also sync your account across multiple devices while using the QR code. It makes it impossible for unauthorized access, even if they know your password as well. 

Google Authenticator Features

Intuitive User Interface

The intuitive user interface within a user-friendly layout offers a simple process that everyone can utilize for generating 2-step verification codes. You need only to enter your account credentials and get the 2-step verification on it. After applying the generated setup, the account will be inaccessible, even if you have entered your usual password. You are asked to enter a verification code with your password to log in. 

Offline-based Codes

The support for time-based and counter-based code generation enables users to manage the main types of one-time passwords available for online services. In this way, you can protect multiple accounts that handle the standard approach to two-factor authentication. You can generate the codes without connecting your phone to Wi-Fi or mobile data, and they can work, even when your device is offline. 

Improved Performance

The app supports Android devices version 4.4 and above, and is available for free download. It supports more than 40 languages for you to understand it easily, and is used by millions of users in around 150 countries. You can use it for all of your Microsoft accounts, and also, there is no need to use the QR code, as it is necessary in the Google app.

Avoid Unauthorized Access

The app requires no internet connection; instead, you can carry on more securely compared to SIM-based authentication. It helps to avoid unauthorized access and prevents attackers from intercepting the verification process. You need to navigate to the service that you want to secure by simply scanning the QR code scanning, or manually entering the code, and let the app generate fresh codes after thirty seconds. 

Synchronization & Backups

The app offers seamless synchronization for multiple devices, and you are capable of syncing your codes with your Google account. After enabling the code within your Google account, it is possible to restore the code for other devices that have the same Google account. In this way, you can save your devices, even in case of losing or replacing your phone. In addition, the QR-based transfer system helps users to export their set of accounts as a QR code and import them to other devices, similar to manual backups. However, the software isn’t equipped with a lock screen or password, and relies on device-level screen lock features of Android. 

Enhanced Protection

The software proves to be one of the most powerful authentication tools to offer awesome services for multiple platforms, such as email services with cloud storage accounts, banking applications, social media platforms like Facebook, and so on. The lightweight protection and efficiency are the major elements to get highly standard security for your accounts. Compared to SMS authentication, it strongly suspects attackers. 

QR Code Integration

The QR code scanning is the best solution to avoid typing errors, making the setup quick and simple. You need only to scan the QR code available on the service, and you can sign in, as it will approve it within seconds. You need to allow camera permission for the purpose. After configuration, you need to move to manage the app. The multi-account support enables users to keep verification codes to handle multiple services simultaneously. Simply click and hold down any entry to copy the code, and boost the login process. Simply long-press the entries and rearrange them, or drag them up or down, and keep the mostly used accounts at the top.
