mOTP - mobile OneTimePasswords!

This application lets you generate One Time Passwords that are used for a more secure authentication (two-factor) - instead of having to enter a static password the iPhone plays the role as a security token that generates passwords that are valid only one time. The authentication mechanism is based on two factors: - the token device (i.e. mOTP-Application) and- a PIN Since the generated passwords are only valid for a very short time - it is of no use for a possible attacker. Note:- the server you want to log onto also needs to implement the OTP-algorithm, you need to configure your shared secret/PIN there- the secret key is generated using random by shaking your iPhone :)- the algorithm uses MD5-hashing- compare this solution with Mobile-OTP Midlet solution on http://motp.sourceforge.net/- also free server components to be used e.g. as PAM can be found there.- the clocks of your iPhone and your Server have to be in sync- the algorithm can also be used for implementing a challenge-response authentication i.e. the PIN is not fixed but a random number is provided to you by the server at the login prompt.
