Is it possible to do the following with Wordpress (without hacking too much code - I would like to make this a general plugin using simple hooks)?
- Log in with the username/password.
- If username/password correct then have another authentication step (a token or a question).
- If token is also correct, then give user access.
For those of you that have bank accounts with Bank of America, this is very similar to their "sitekey" login system. If anyone has any tips or plugin examples, don't hesitate to link them. Thank you!
This is virtually identical to the following question: http://wordpress.org/support/topic/two-step-authentication-login-needed on the official forums.
