Definition: OTP (One-Time Password) (Part 3)
A unique, temporary code sent via SMS to verify a user's identity during logins or registrations.
A One-Time Password (OTP) is a dynamically generated security code that authenticates a user for a single transaction or login session. Unlike traditional passwords, OTPs are valid for a very short period (typically 2 to 20 minutes) and protect accounts from unauthorized reuse. Using a virtual phone number to receive OTPs is a common privacy best practice to avoid exposing personal numbers to trackers.
