mOTP - mobile OneTimePasswords 1.4

This application enables users to generate One Time Passwords to enhance authentication security through two-factor authentication. Instead of relying on a static password, the iPhone acts as a "security token," creating one-time passwords for each use.

The authentication process involves two factors:

• The token device (e.g., mOTP application)
• A personal identification number (PIN)

Due to the temporary validity of the generated passwords, they offer heightened protection against potential attackers. Additionally, passwords can only be created with both the PIN and the token device in possession.

Key points to consider:

• The target server must also support the OTP algorithm, requiring users to set up and configure their shared secret/PIN accordingly.
• The secret key is randomly generated by shaking the iPhone.
• The algorithm utilizes MD5 hashing for password generation.
• For an alternative solution, users can explore the "Mobile-OTP" Midlet solution at motp.sourceforge.net, which offers free server components like PAM integration.
• Your iPhone's clock should be synchronized with the server's clock for optimal functionality.
• Furthermore, this algorithm supports challenge-response authentication, where a random number provided by the server serves as the login prompt rather than a fixed PIN.
