I am trying to set up email confirmation voting, since its the most accessible for all people. Now I am wondering if a user voted on day 1 on a certain option and then wants to return 3 weeks later to the poll to vote again with the same email, is this possible? How can he vote again with the same email?
Whether a user can vote again with the same email after some time depends on how we can identify them when they return to the poll.
If the user has a PollUnit account and is logged in, we can reliably recognize them, even after several weeks and across different devices. If the user does not have an account, we try to recognize them based on technical identifiers like cookies. This means they need to use the same device and browser as during their first vote. If they do, and the cookie is still present, they can vote again. Otherwise the user can not vote.
If a long timespan between votes is expected, we recommend using the »PollUnit account required« security setting. This ensures that users are always recognized via their account, and the email address is confirmed as well.
Thanks for the fast answer, that helps.
