Yes, but I have to admit that I didn't record the exact error ... I would say that my validation code was no longer valid at the time of submission, and then I tried to re-generate one without changing the registration TOP code... Sorry I wasn't very conscientious about evaluating the error.


But finally, I found it confusing to have to create this two-factor authentication directly on the account creation form ... From an interface point of view, it might be more smooth to provide it on a second step, maybe after email confirmatinon page ?
