Entering very long Google password during setup If I have a new phone how can I enter my Google password in a secure manner during setup without having to type it (it is VERY long at over 30 random alphanumeric characters and a pain to type). 

Since the phone it not yet set up I have no way yo send it to myself from another device via encrypted email, messaging, PGP because I have no apps installed yet.
Well technically I don't think you need to actually setup a Google account right away. So what I would recommend is skipping the part of the setup process where you setup a Google account and then use a built in app to retrieve it (SMS, copy a file onto your phone or any method to read text).

Other than that I think the best thing would be to just temporarily change your Google password for a few minutes, than change it back right after (once you have methods to get the new password onto the phone without typing)
