@OP, So I upgraded last night and had no problems so far. Finished playing and closed the window from lobby but did not click the ''log out'' button. Switched off the laptop. Today I clicked the launcher (desk top short cut), and I was still logged in and had to type nothing. Not sure how long active sessions run for but guessing 24 hours if they are still using the old system.
As for the forums I still had to log in (from browser) even after I was already in game, but auto type login works and only had to give the email code.
Do not use auto type login or stay logged in if you are using a shared device but that's just common sense.
Would be nice if they could just add a cookie to my device like banks do so not to get a verification every time to use forums.
Not sure why its crashing for you but make sure you are not using the old Runescape launcher at the same time as the new Jagex launcher.
The old system you had to type the password manually. Now you can have a crazy long password and just let auto type fill it in for you.
