Google Authenticator: Best for secure offline authentication
Google Authenticator is a multi-factor authentication app that generates unique, time-sensitive codes to enhance account security. The app works by generating time-based one-time passcodes that users enter in addition to their passwords when logging into their accounts. These passcodes are secure as they are generated locally (on the device) and not transmitted over the internet.
In 2023, Google Authenticator was updated to include backup capabilities through cloud syncing. However, users have reported issues with this feature.

How to choose the best authentication apps
In choosing an authentication app, organizations must take into consideration their size, existing structure, budget and specific security needs. For example, an organization with fewer than 500 employees would underutilize the YubiEnterprise Subscription because of its physical keys. If you need an authenticator app that offers different types of authentication and works on multiple devices simultaneously, you can opt for Authy. If your priority is an open-source authentication app for easy customization, you should consider FreeOTP. If you want to tilt toward a hardware authenticator or physical keys, then the Yubico Security Key is your best bet. Keep in mind that each of the reviewed authenticators delivers quality services, but each tool’s utility will depend on your authentication needs.
Methodology
For this review, I considered some key features of these solutions, focusing on their security details, accessibility and performance. Having obtained ample information from the vendors’ websites, I also checked for user feedback for the paid solutions. For firsthand experience, I reinstalled Google Authenticator and used it to power 2FA for my Twitter and Facebook accounts and also Microsoft Authenticator for my Outlook account. While it was quite easy to navigate the Google Authenticator with its simple interface and TOTP, security was tighter with Microsoft Authenticator as I needed to use biometrics to see the codes generated for each account log-in attempt and I also had to enter the code on the account seeking access.
