I am using keyauth from 2024 and this is best and easy to use
By Mian Usama R.
Honestly keyauth is probably the best auth service out there right now. I’ve been using it for my modding software and it’s actually insane how good it is. Prices are fire: The pricing is rly good, plus the fact that you can test everything out before buying anything is so good. i tested dev and Seller tier and chose dev because using seller just had no Sense for me. Super fast: Server side performance is super fast and no lag at all. The application UI is super clean too, making it easy to manage everything. The easy HWID reset helped a lot and saved time for me :) Code examples: The code examples made setting it up so easy, shit saved me so much time. Support: Haven't even needed to open a ticket once because everything just works, but ik their support is good anyway. If you’re looking for a good key system just use KeyAuth. for the keyauth team, i love yall please keep doing this great stuff! :)
