Could be betterAlthough Authy requires a phone number and sends a text message with an activation code, it doesn’t offer the most secure setup process. Moreover, since Authy tokens are saved in the SIM card, it’s safer always to use the Google Authenticator token instead. Nonetheless, it does provide the option to protect the app with a PIN, providing its users with an extra layer of security.Google Authenticator entirely discards desktops from the equation, with no support for Windows, Linux, and macOS. Additional security is one of the weak points of the bare-bones Google Authenticator app. Google Authenticator has no encrypted recovery backups.
Key features1) With Authy’s multiple-device functionality, your 2FA tokens automatically sync to any new device you authorize. And, if a device is lost, stolen, or retired, you can deauthorize it from any authorized device just as quickly. 2) Since Authy is available for Android, and iOS mobile devices, and for Windows, Apple Watch, and even your desktop 3) Authy enables a PIN and biometric authentication like TouchID to protect data against unauthorized use.Simple, user-friendly Google Authenticator may not have a modern UI, but the minimalist style makes it extremely easy to use.

Feature Description

Available on Multiple Platforms – Multi-Platform means being able to run software on more than one hardware platform. So, that software can be used by different users using different hardware platforms. Google Authenticator is only available on mobile devices while Authy provides its app on PC, Mobile and Chrome devices.

Encrypted recovery backups – Securely back up 2FA tokens and restore them if you lose your device. Authy offers a unique and optional way to make a backup of your 2FA recovery codes: an encrypted Cloud-based backup. When you enable the Authy backup feature, your phone encrypts all your existing 2FA account data locally before sending it to Authy’s cloud servers to be stored. You are then required to create a key to decrypt your data. This feature is mainly presented on Authy, while on Google authenticator it is absent.

Push Authentication offers a seamless user experience for second-factor and passwordless authentication and offers the highest level of cryptographic security. By using push notifications, OneTouch displays more information during the authentication, aiding the user in the decision-making process. For users with the ability to install an app on their mobile device or computer, these ApprovalRequests can be sent and verified.

Different types of passwords – is a feature described by using multiple ways to encrypt fragile data. Commonly, it is been presented by one master PIN at the starting screen of the app, which protects your data (tokens) from potential theft. Authy provides different layers of security whereas Google Authenticator does not.

Alerts/Notifications
Users may receive a “Security Alert” notification email when adding a new device to an Authy account. The alert email includes the device name and location to help you identify it as an approved device. It adds an additional security layer to your fragile data. Both Authy and Google Authenticator have it.

Multi-Factor Authentication is an authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN. MFA is a core component of a strong identity and access management (IAM) policy. The main benefit of MFA is it will enhance your organization’s security by requiring your users to identify themselves by more than a username and password. While important, usernames and passwords are vulnerable to brute-force attacks and can be stolen by third parties. MFA works by requiring additional verification information (factors). One of the most common MFA factors that users encounter is one-time passwords (OTP). OTPs are those 4-8 digit codes that you often receive via email, SMS or some sort of mobile app.

Biometrics – A biometric factor is something inherent in the user’s physical self. These may be personal attributes mapped from physical characteristics, such as fingerprints authenticated through a fingerprint reader. Other commonly used factors include facial and voice recognition or behavioural biometrics, such as keystroke dynamics, and gait or speech patterns.
