S9+ Two factor authentication issue

[NikhilChandra]

Hi,

My phone forced me to turn on two factor authentication to use samsung cloud sync.

Now, I am unable to use my account. I'm not getting SMS also. It showing "Failed to send SMS". 

Samsung team, if you are not willing to send SMS, why did you implement junk idea on my phone?

I tried to turn off, it's not allowing me to do that also.

What's wrong with you people?

Samsung has made it mandatory to use two factor authentication for using Samsung cloud. otherwise, you can't use samsung cloud
