Not sure what you are talking about. Can you describe your problem a little bit clearer? What are you trying to do exactly? What do you mean with one-time password?
I answer at the LimeSurvey forum in my spare time, I'm not a LimeSurvey GmbH employee.
No support via private message.
Wouldn't it be a good start to tell us what version of LimeSurvey is used and a screenshot where you miss buttons or forms?
LimeSuvey is lacking a way to prevent sending passwords via email. That should be changed.
