I've tested a couple of other plugins but they simply didn't work or only worked well with their premium versions.
This plugin worked great for Google and Facebook login (only tested this two). Easy to style and worked great with minimum effort.
Appreciate the efforts of the developer. Miled has made it clear in the documentation that this is a labour of love and they may discontinue support at any time. Unfortunately it seems that time has come. The plugin no longer works with Wordpress 5.4.
