After foolishly turning on the two-factor identification I can no longer receive my email? Any help would be appreciated.

After foolishly turning on the two-factor identification feature on my iPad it appears I can no longer receive my email. I was tricked into doing it when told I must reinter my password and then it refused to accept my password, even though I know it was right. In the process of changing my password the slipped in the two-factor Id, which at the time seemed like a good idea. I did not realize I would not be able to turn it off or that it would affect my email.
