Thanks for the idea. I wonder if that idea isn't better implemented as a separated PAM module though? Is there anything OATH related to the concept of a PAM module doing "emergency scratch codes"? It appears less complex to have that functionality as a separate module. And that should be more flexible too. I am sorry but I don't have time to work on creating that PAM module now though, but it shouldn't be too hard.

I'm leaving this open as a reminder to create such as a PAM module. Or to revisit my preference for not solving this in pam_oath.

Thanks.

Add the ability to use emergency scratch codes in the PAM module, to allow access in case of counter desynchronization or time configuration error, such as google-authenticator does. See https://wiki.archlinux.org/index.php/Google_Authenticator#Generating_a_secret_key_file for UX example. The codes could be stored in the file the same way as the usersfile. The module would delete used codes. The codes could be user-dependent or not. It would be ideal if the PAM module could warn the user if few (1 or 2) emergency codes are still available.
