A helper component to allow site members to validate their identities when contacting people outside of the site organisation. If a site member is contacting someone via a method that is insecure or not easily verified, such as phone call or most e-mail, this component can allow the person being contacted to validate the member as belonging to the website. A code is generated in advance by the site member and provided to the contact, who can then enter it into a public form on the website to verify its authenticity and the identity of the user who generated it.
