Microsoft Authenticator: Ideal for a ‘big-name’ choice

For individuals seeking a well-established and renowned provider, my suggestion is Microsoft Authenticator. Compatible with Android and iOS, Microsoft Authenticator delivers a comparable experience to Google’s, supporting both Microsoft and non-Microsoft
accounts.
No passkeys are needed. Accounts are reachable using a personal identification number (PIN), fingerprint, or facial recognition. The feature I particularly admire is the ability to backup credentials to the cloud, which necessitates a private Microsoft account, while iOS users also must link to an iCloud account.
Recent significant enhancements introduced by Microsoft include the capacity to display the name of the service, website, or application being accessed. This acts as an additional security measure that you can utilize to authenticate the legitimacy of a Multi-Factor Authentication (MFA) request.
Reasons for Selecting Microsoft Authenticator
In my view, as a substantial, well-established corporation, Microsoft and the Microsoft Authenticator team can offer a strong level of assistance for users encountering queries or problems with the product. It can also provide consistent updates to introduce new functionalities and address any software bugs.

FreeOTP: Exceptional for an open-source substitute

For those who value transparency and privacy, I recommend exploring FreeOTP. An issue with Google Authenticator is its lack of open-source status, with the relevant repositories not being updated for several years. This isn’t a concern with FreeOTP, as it’s entirely open source.
The latest major release of FreeOTP is Version 2. It brought forth a fresh material design interface, default branding for major services, and the option to back up and restore tokens. Subsequently, three minor updates have been rolled out, addressing various bugs and making slight improvements.
Accessible on both Android and iOS, this authentication app is reasonably lightweight and simplistic, both in terms of user experience and functionalities.
Reasons for selecting FreeOTP
As open-source software, FreeOTP can deliver faster updates and resolutions to issues like bugs and vulnerabilities for users. It stood out on my list for its extensive customization capabilities that aren’t feasible with other private or proprietary software.

How can I make a decision between Google Authenticator substitutes?
If you wish to explore substitutes for Google Authenticator to tailor your MFA method, manage multiple devices or users, prefer using a physical security key, or seek a company with various support options, you may want to consider alternatives. While companies providing MFA solutions aim for enhanced account security, variations exist in the level of security and functionalities affecting ease of deployment, utilization, and maintenance.
When choosing a product that fits your requirements, consider your budget and the most crucial features and traits for you. Reflect on variances in provided authentication layers, backup and restore opportunities, encryption protocols, customization, support preferences, and tools for managing user group permissions.
For instance, individuals or businesses susceptible to phishing attempts may value the assurance of a Yubico phishing-resistant security key. Similarly, organizations with employees requiring diverse permission levels might find Cisco’s Duo Policy Engine beneficial.
