Answer
One-Time Password is the English full name of the same concept as OTP: a password/code for a single operation with a limited TTL.
In product copy and APIs people usually write the short “OTP”; in English specifications — “one-time password”. The meaning is the same: the code arrives on the user’s phone and confirms possession of the number.
A full breakdown of scenarios, security, and Cascade integration is in the canonical article “What is OTP?”. Nearby in meaning: verification code (as a UI field) and authentication (OTP as a login factor).
