What is SMS Verification?

SMS verification, also known as SMS authentication, is a security measure that uses SMS messages to verify a user’s identity. It adds an extra layer of security to online transactions, account logins, and other digital interactions on websites and apps.

Traditional password-based authentication has proven to be ineffective against modern cyber attacks. Studies reveal that 96% of the most common passwords can be hacked in less than a second. Even when people follow best practices, passwords can be stolen through social engineering. This is why businesses widely implement two-factor authentication (2FA), which makes unauthorized access more difficult even if a user’s password is compromised. SMS-based 2FA utilizes text messaging to deliver authentication codes to users’ mobile phones, enhancing account security.

How Does SMS Verification Work?

SMS verification requires users to confirm their identity through a unique, temporary code sent to their mobile device via SMS. By introducing this additional step, SMS verification codes significantly reduce the likelihood of unauthorized access and bolster defenses against cyber-attacks.

The steps involved are:

1. The user is prompted to input their phone number during the account sign-up or registration process on the business website or app.
2. The user's phone number receives a code, which must be entered into the designated field.
3. For subsequent login or transaction attempts, after entering a username and password, the user will receive a unique code or one-time password (OTP) via SMS on the designated phone number.
4. The user inputs the code and gains access to their account or completes the transaction.

What Does "SMS Authentication" Mean?

SMS Authentication is a form of identity proof commonly used for two-factor authentication (2FA) or multi-factor authentication (MFA).

In SMS authentication, the user provides a code sent to their phone via SMS as proof of their identity.

In theory, SMS authentication provides a second identity factor. While usernames and passwords represent something that only the correct user knows, an SMS code sent to a specific mobile device is evidence of the possession of something (a specific mobile phone) that only the authorized user should have.

However, SMS authentication is not without its flaws. The world's SMS systems are notoriously insecure, having been designed and deployed decades ago when cybersecurity was not a primary concern. SMS infrastructure often lacks authentication, transmitting data in plain text, making it susceptible to interception and eavesdropping. Additionally, phone numbers themselves are generally unsecured and easy to steal, spoof, or port.

For these reasons, most experts do not recommend heavy reliance on SMS codes as an authentication factor. Despite its weaknesses, the ubiquity of mobile phones and users' familiarity with them have led many organizations to adopt SMS authentication as the path of least resistance to 2FA or MFA compliance.
