I recommend Keyauth for everyone who needs a keysystem. Its so easy to set up and connect to your project. The prices are insane and it's totally worth it. I like the amount of features you have with keyauth and they still release new one. They also have a big amount of examples about using keyauth in your project. The only thing what i miss is a example for javascript. Hope it will be added soon. -- Displayray

Weebzo My experience with keyauth has been very great so far, the owner actually reads suggestions and bugs that you find and you can say this the 1# best authentication service out right now 🙏. Plus all the reasons it offers, customer panel, chat for your applications, seller api to manage keys of your application and how simple it is to setup, since it already has already coded SDK's for PHP,Python,C++,C#,Rust ans VB, you can also make your own sdk for lenguages that don't have an available sdk. In conclusion this the best auth service you can get right now for so cheap, if you don't have a paid subscription to use all its features get it when you can since its so worth it🙏🙏🗣️💯.
