Hi Rob
First off, this review should be obviously removed, since it’s not about Rublon the plugin.
The Rublon for WordPress plugin is just a bridge between your WordPress website and the Rublon API, which is being used in many different ecosystems, not only WordPress. We have been offering a broad access to the Rublon API for free for a long time with free support in exchange for feedback that helped us to improve the product. It is normal that services like Rublon cost A LOT of money to build and maintain and this is why Rublon for WordPress requires paid access to the Rublon API if you’re running a business on WordPress. We have taken a look at our stats and the vast majority of websites are not affected by this API limitation since they have only 1 user (the admin).
If you’re not satisfied with Rublon, go ahead and find an alternative —?I can only assure you that you won’t. We are the best 2FA solution on the market and our prices are very very competitive compared to different solutions. Security has to cost money because it has to be maintained every day by professionals.
All the best
Rublon Team
