Are you sure that you are not using a modified client?

No mates...

i just downloaded the minecraft installer from mojang website after purchasing it and i only added optifine to increase my fps for the game nothing more.

Optifine IS a mod, so you do use mods

If your Mojang account is linked to your Twitch account, try disconnecting it. Seems to have fixed this issue for a few people.
