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.
This application serves one purpose only. It calculates and prints a OTP.
Most people use OTPs to log in to their website administration, CMS, or remote console.
No. Google uses OTPs, but in a slightly nonstandard way. OTPWCalc cannot calculate OTPs useful for Google authentication yet.
Yes, but some work is needed on the Windows/OSX/Oracle computer to configure the authentication subsystem.
Yes, by using PAM and it's quite easy.
OTPWCalc might not be compatible with your platform of choice, usually because the necessary hardware isn't available to the author for development.
Take a look at the entry point in main.js:
var secr = $('#paswrd').val();
var resp = hash(secr, user, iter);
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.
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.
Yes. Custom built enterprise versions are available accompanied with commercial support. Visit the OTPWCalc homepage for information.
Maybe, but spies probably just look over shoulders or use cameras to steal the static passwords used in OTP systems.
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.
This varies according to the operating system used so there's no single answer.
