OTP (One-Time Password)

A short, single-use code sent to verify a user's phone number or authorise an action.

An OTP (One-Time Password) is a short code, valid once and briefly, sent by SMS, WhatsApp or voice to verify that someone controls a phone number or to authorise a transaction. Fast, reliable OTP delivery is critical for signups, logins and payments; multi-channel delivery with fallback keeps verification working even during network congestion.
