A one-time password is a unique, time-bound code used to authenticate a user or transaction, adding an extra layer of security to digital payments and banking.

OTPs are sent via SMS, app, or email and must be entered within a short time window. They prevent unauthorised access even if credentials are compromised.
OTPs reduce fraud risk and protect sensitive transactions. They are widely mandated for financial security in India.
Secure authentication improves trust and compliance across digital financial systems.
