[Q] Log into Hangouts without adding the account to the full sync
I have a personal Google account which I sign into my Nexus 5 with and that all works fine.
I also have a work Google Apps account which I would like to log into Hangouts with but do not want to add it like a normal account (i.e. Settings > Add Account etc).
The reason is that if I sign in to my work account it requires that I download a device policy which then restricts how I use my phone (i.e. does not allow lock widgets, rooting etc).
I have found workarounds for email and calendar where I have third-party apps that let me sign in from a web-based google login page and then grant access.
So I am after, either, a way to log into Hangouts app without adding a base account, or a third party app maybe that would allow me to log in like the email / calendar clients I have.
Any suggestions for this would be appreciated.
