 873                 E-mail address authentication uses a scheme to authenticate e-mail addresses of the users. The user who initially enters or who changes his/her stored e-mail address
 874                 gets a one-time temporary password mailed to that address. The user can use the original password as long as wanted, however, the stored e-mail address
 875                 is only authenticated at the moment when the user logs in with the one-time temporary password.<p>
 876
 877                 <p>The e-mail address stays authenticated as long as the user does not change it; the time of authentication is indicated
 878                 on the user preference page.</p>
 879
 880                 <p>If the option is enabled, only authenticated e-mail addresses can receive EmailUser mails and/or
 881                 e-mail notification mails.</p>
