A One Time Password (OTP) is a password valid only for a single use and, once used, cannot be used again for authentication. OTPs avoid a number of shortcomings that are associated with traditional (static) passwords.
michael@4:This application serves one purpose only. It calculates and prints a OTP.
michael@4:Most people use OTPs to log in to their website administration, CMS, or remote console.
michael@4:No. Google uses OTPs, but in a slightly nonstandard way. OTPWCalc cannot calculate OTPs useful for Google authentication yet.
michael@4:Yes, but some work is needed on the Windows/OSX/Oracle computer to configure the authentication subsystem.
michael@4:Yes, by using PAM and it's quite easy.
michael@4:OTPWCalc might not be compatible with your platform of choice, usually because the necessary hardware isn't available to the author for development.
michael@4:Take a look at the entry point in michael@4: main.js:
michael@4:
michael@4: var secr = $('#paswrd').val();
michael@4: var resp = hash(secr, user, iter);

michael@4: In other words, the password you enter is neither stored nor transmitted. In fact, OTPWCalc doesn't store or transmit any data input at all (see James Bond question later.) It's a calculator in the true sense, just like a pocket calculator that adds numbers.
michael@4:The algorithms of OTP have proven worthy of high security applications. OTPWCalc has been carefully designed and is tested thoroughly. It's both secure and safe to use.
michael@4:Yes. Custom built enterprise versions are available accompanied with commercial support. Visit the OTPWCalc homepage for information.
michael@4:Maybe, but spies probably just look over shoulders or use cameras to steal the static passwords used in OTP systems.
michael@4:Yubikey, RSA SecurID, and OTPWCalc use similar technologies for similar applications, but OTPWCalc is strictly software and doesn't depend on the time or date.
michael@4:This varies according to the operating system used so there's no single answer.
