Thanks for this! I pulled and added a couple specs and made a minor change so you can pass an integer or string to the validate_code method. |

Consider the user enters the validation code "012345". The list of
valid_codesinUserSessionController::validate_codewill containROTP::TOTP.new(two_factor_secret).now, which is the integer12345. When you call.to_son that integer, you'll get "12345"."012345" != "12345", so even though the code was correct, validation fails. The solution outlined in my pull request calls.to_ion the validation_code that the user passes in and no longer calls.to_son the validation codes computed by ROTP.
