Early december I decided to delete the gmail account thinking that I would not lose that awfully much. Now I realize that I cannot access my files on p5js online editor since I used Google to login. My bad. Is it possible to access the files anyhow? Have them transferred to a new account?
If you can’t recover your Google account anymore and there’s no any other way to log in on P5, an option would be to contact an administrator of P5. Behind the scenes they might be able to change your login information. I would save this as a last resort though.
