RPs should allow users to bind multiple identifiers to a user's
account, and allow users to add and remove them.<br>
<br>
For most consumer oriented websites, account recovery via verified
email address is probably the most realistic option. Many users have
problems remembering their secret questions, and the secret answers may
change over time. (Your favorite movie might change) Additionally, many
the answers to many secret questions might not be all that secret.
