Double Opt-In Helper is a WordPress plugin that helps developers implement the double opt-in process in their plugins.
What is double opt-in?
Double opt-in is a procedure used to confirm users’ consent. Today, service providers are often required to obtain clear consent from users before collecting or using their personal data, and in some situations, asking the user to tick an “I agree” checkbox is not sufficient. Double opt-in serves a useful role in such situations.
A typical double opt-in process starts by the service provider sending an email message to the user. The message includes a URL link to the provider’s website and asks the user to click the link if they agree on conditions. Usually, the URL includes some sort of unique random code that works as a token to confirm the user’s consent.
By doing this, the service provider can confirm that the real user (not a bot or someone else) has consented, because only the user should be able to access messages to their email address.
