Can i use a rockstar account for all rockstar studio games?

The only verified source supplied discusses Grand Theft Auto V and does not mention Rockstar account policies or cross-game usage. Because there is no evidence available in the data, it is impossible to confirm that a single Rockstar account can be used for all Rockstar Studio games. To determine whether a single account works for multiple titles, you would need to consult Rockstar Games’ official documentation or support resources.
