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! :)

Everything was gold in 2025, but last few updates in 2026 he added 'feature' that clean his DB. What i mean? Lets say you make 50 keys send them to seller, everything slowly selling all fine, but suddenly i got reports 'i got key that not working`, okay werid right? I visit cabinet to see logs and not found any, asked support got answer there is no logs for keys. Ok i asked why key disappeared, in answer i got `we have auto key clean if they not active in 3 month` Um, alright maybe thats required to keep DB size in fine tune thats kinda fine. But issue is key that disappeared created in this month, so i made another ticket about this issue in march, and after 5 month this *unspeakable disapointment about issue* still exists and active. You send few batches to sellers and half of keys burn under month or maybe two and developer have no idea why and how. So keep with keyauth if you totally not want make own licensing even with AI, otherwise consider of making own, or just buy keyauth source and host own without key removal. (As i understood right he selling it btw i currently not see this offer on site anymore but try ask support.)

Hello, thank you for your review. To clarify, back in 2025 we were still doing auto-deletion (cron jobs). This is to ensure people aren't creating thousands of keys and are just letting them sit. This also helps us to prevent a key limit for paid users. Without cron jobs, key amounts could be limited. Application developers can use the seller key to provide keys directly upon purchase, that way keys aren't just sitting and risk being deleted. Resellers will soon have their own system to auto deliver keys as well, we will have a Reseller API which will allow them to place it in an e-commerce system just like how devs can with the Seller API. This will help resolve storing keys in bulk. We do not sell the source anymore. We stopped a little over a year ago if I recall correctly. Thank you for your time!

The site has terrible mechanics and cannot handle simple problems. I just changed my username, and the username was binded to another account, and they didnt alert me of that. And so the password is now wrong. This app/website is terrible. Dont use it.

Hello, Thanks for bringing this to our attention. However, I may be misunderstanding something. We have safeguards in place to ensure usernames and be used more than once. Was this with a normal sign in, or using a social sign in, like Discord or Google? We would be more than happy to help you get back into your account. It doesn’t appear that you’ve created a ticket about this yet. Please reach out. Thank you 😁
