What does OTP mean in banking?

Written by Editorial Team | Last Updated: August 2026

In banking operations, cybersecurity protocols, and customer account management, OTP stands for One-Time Password. Whenever a bank customer attempts to log into their online banking portal, add a new payee, or execute a high-value wire transfer, the financial institution's security system generates an ephemeral, time-sensitive numeric passcode sent directly to the user's verified mobile device. Entering this OTP verifies the account holder's identity and authorizes the secure transaction safely.
