Google enforcing two factor Authentication

[king1]

Just saw an email today that google sent to a client, will be turning on Two Factor authentication by default as of Nov 9.  
Will still be able to disable it for now apparently but will be permanent in due course.  Anyone else seen this?  Haven't had one for my account yet.  I can imagine that is going to cause a few people some problems accessing accounts...

I dont have 2fA and am yet to receive any email

interesting just been to an appointment and that was the problem... maybe they are being selective about it or introducing it over a period of time
