What is SMS verification and how does it work?
SMS Verification Process
The SMS verification process is a step-by-step method that ensures secure user authentication. A recent study highlights that 93% of enterprises globally depend on SMS one-time passwords (OTPs) for verification purposes.
1. OTP Creation and Delivery
When a user initiates a login or performs a sensitive action, the system generates a unique, time-sensitive OTP, typically a six-digit code. This code is then sent via SMS to the user’s registered phone number.
To maintain security, the process includes:
- Random code generation: Each OTP is created using secure and random methods.
- Short validity period: Codes expire quickly to reduce risks.
- Rate limiting: The system restricts the number of attempts to prevent misuse.
Once the code is delivered, the user must input it to complete the verification process.
2. Code Entry and Verification
After receiving the OTP, users must enter it into the app or website. Speed matters here – 61% of users expect these messages to arrive within one minute, according to the 2024 Customer Connections report. The system then compares the entered code with the one it generated.
If the codes match, the user’s identity is verified, and they can proceed.
3. Access Confirmation
SMS verification is highly effective in protecting against various cyber threats. A Google study found that SMS verification codes successfully block:
| Attack Type | Prevention Rate |
|---|---|
| Automated bot attacks | 100% |
| Bulk phishing attacks | 96% |
| Targeted attacks | 76% |
To further enhance security, the system enforces limits on the number of verification attempts, reducing the risk of brute force attacks. This combination of features makes SMS verification a reliable method for safeguarding user accounts.
Security Benefits of SMS Verification
SMS verification plays a vital role in safeguarding digital platforms. With over 76% of organizations worldwide relying on SMS-based two-factor authentication (2FA), its popularity stems from its reliability in protecting user accounts and sensitive data.
