A One-Time Password (OTP) message on the Android operating system refers to an automatically generated string of characters or numbers delivered via SMS. This code serves as an additional layer of security, requiring verification beyond a username and password combination when accessing online accounts or completing transactions. A common example involves receiving a six-digit code on a mobile device to confirm a login attempt to a banking application.
The use of these SMS-delivered passcodes strengthens security protocols by introducing a dynamic element, mitigating risks associated with compromised or stolen credentials. This security measure gained prominence as digital transactions and online account management increased, addressing vulnerabilities inherent in static password systems. The incorporation of this practice is a key element in fostering trust in digital platforms.
