Restore gmail account to Android I just got a new Motorola Droid Turbo 2, Android 5.1.1 I have 2 gmail accounts &amp; 1 just disappeared (it was there as of yesterday), altho I can access it from any computer. I have tried to add the acct by doing the obvious: "Add Account" on my gmail page, and "Add an Acct" in Android settings w/no luck. Both seem to be treating it like I'm trying to establish a new acct not an existing one.
Storing this for future reference and to help others.

Summary


2 (multiple) gmail accounts
desktop computers fine
android mobile phone


1 gmail account accessible the other not
had removed google authenticator 4 months ago on previous mobile

new mobile 1 month ago


  everything syncing and accessible till recent google account password change



Actions


tried cache apps deletes, reboot
tried google resync
then tried android mobile google account remove of non-accessable gmail account
successfully installed google authenticator on mobile by switching to working google acount via desktop computer
then tried disable 2 step authentication
then tried changing google account via lastpass (wanted one common password for both google accounts) which failed
changed google account password successfully via google account. Rebooted mobile. Waited 1/2 hour for servers synching.
Now able to logon to both accounts on mobile.


Notes


only using lastpass on desktop and not mobile device 
google server synching most likely much quicker than 30 minutes
I have not tried individual google account passwords yet
I have turned google account 2 step verification back on
I have not setup google authenticator app yet
