Hello there I had recently encountered a problem where I wasn’t able to check if a Roblox cookie is valid or invalid and I was suggested by a friend to use an API but the result isn’t satisfactory as it takes time.
I was wondering if there was anyway to check which wouldn’t involve any sort of API
Then there’s no different option. You cannot just validate a cookie without contacting Roblox api in any way. Even if cookie format is appropriate, tokens do expire.
