Turn off 1 time password and dont log out when you quit, just let it go to sleep or put it in sleep mode. You will stay at start screen and be able to go right to character select. I have been playing on PS4 and PS3 since ARR and play every day. Every once and awhile it will kick you out and make you go from the start, but I only have to log in once or twice a month and my ps4 times out after 1-2 hrs of inactivity. I switch to Netflix alot and come back and just character select. This option is not needed in my mind. Now if you're playing other games inbetween this doesn't work.
