    ... for e-banking web apps two-factor (or even three-factor authentication) should be implemented (at least) for performing actual transactions.

    One way to do this are one-time-passwords (...TAN...).

    Before, you as an end user could select at your will which TAN ... to use.... Nowadays (presumably because users were ... writing them down .../storing them on PDAs or whatever) the banking apps requests you provide a TAN specified by row and column....

    I would be happy if my bank would just start using an https login page, but they insist on having a login form on their home page, which is just delivered over http.

    Regarding the TANs, I don't see how specifying row and column would stop the users from storing them on their PDAs; they would just have to store a list of row+column+TAN. Presumably specifying the row and column is done to force the user to prove they have access to the entire block. Although the more I think about it, I'm not sure of the value of that for security.

    From our code:

    public bool IsUniqueLogin(string username) { bool isNewUser = true; foreach (ProfileEntity user in service.GetAllProfiles()) { if (user.Username == username) { isNewUser = false; break; } } return isNewUser; }

    Aside from the WTF with the where clause...

    I liked the fact that this.authenticated = false; gets called for every record that doesn't match.

    OMG I didn't even notice that.

    Life   --- By Allan Houston   Life can be good,   Life can be bad,   Life is mostly cheerful,   But sometimes sad.   Life can be dreams,   Life can be great thoughts;   Life can mean a person,   Sitting in court.   Life can be dirty,   Life can even be painful;   But life is what you make it,   So try to make it beautiful.
