FreeRADIUS is completely scalable and supports both large and small user databases. Because it doesn't take up a lot of server resources, FreeRADIUS is well-suited for organizations with small budgets (it's in the name!) and limited networking hardware. While there is a port of it for Windows, FreeRADIUS is native to Linux so that would be a limitation for many companies who don't use it.
Logging into my work accounts is where Google Authenticator works best. Also, I had a personal account get hacked. I had an account created to book hotels, but someone was constantly resetting my password. To prevent further hacking attempts, I set up Google Authenticator. I do not believe it would be appropriate for banking accounts.
I once performed a factory reset of my smartphone which had Google Authenticator. I didn't have a backup for the device. When I restored my phone with the same google account, I was not able to restore the authenticator app settings. I had to add all the keys back into the app to use it. This is cumbersome, but I understand it is set up this way for security reasons.
I don't like the ease with which it lets you delete a key. If I accidentally delete a key, I am doomed to get my 2FA key reset, unless I still have the QR code saved somewhere.
It's as easy as opening the app and what I need it for is there. I don't have to fumble with other accounts or getting something else to open it for me. I have all the access that I need for the use of the app within seconds and I can get access to the info that I need.
I have found Google’s support to be hit or miss. There are times when they are very responsive, and I get my issue resolved quickly, and there are times where a response from them takes weeks. There is no in-between. But my support experience with this particular product is nonexistent because I have not had a problem with it yet. Hopefully, we do not have any problems with it either.
First, Google Authenticator meets the security requirements which should be considered "table stakes". Second, simplicity is critical. Many users don' understand why they are setting up MFA (or they just don't care), and so adding additional complications to their day-to-day is always challenging. When it is simple, it makes life a lot easier. Finally, trust (due to the brand name recognition, primarily) removes any notion of "what is this?" that the user may have from being required to install something on their personal device for work purposes.
We previously used Microsoft Network Policy Server for our RADIUS authentication which works ok but was pretty clunky and requires Windows Server. Switching to FreeRADIUS brought our cost down to zero.
Because FreeRADIUS works natively in Linux it's easy to setup and works with all distros.
FreeRADIUS allows us to have user authentication for wifi which is much more secure than a simple shared password solution.
More secure data = less worried about a data breach.
Takes longer to log in, and if I don't have my phone then I have to go looking for it, so it really makes it so that you can't be without your phone, which in certain instances is annoying or not possible and can hold up work time.
Everyone is willing to use the same program because everyone likes Google—makes it easier to manage.
