Depends if you trust whatever application you are trying to give access to your account details.
so it is just to track my GTA info or information about what i am doing on PC even when FiveM is not running ?
i accidently closed so now i cant authorize and now i dont know what to do now
No, it’s asking you for read and write permission on your forum profile for certain actions. If an official FiveM app is asking you this then it’s completely fine.
In the end this is about you not being dumb and giving access to your account to an application you have no clue what it is and does
oh thx have a good day
