In the world of digital security, user authentication remains one of the most critical challenges. Every day, millions of people log into websites, apps, and services, relying on various methods to prove who they are. Two of the most talked-about methods today are SMS OTP (One-Time Passwords sent via text messages) and passkeys, a newer technology gaining traction in 2024. But which one really offers better security? And why are security experts still debating the relevance of SMS OTP in the era of passkeys? Let’s dive into this topic to understand the strengths, weaknesses, and practical implications of both.
What is SMS OTP and How Does It Work?
SMS OTP is a method where a user receives a unique code on their mobile phone every time they try to log in or perform sensitive actions. This code is valid for a short time only, usually a few minutes. SMS OTP has been around for many years, becoming a standard second-factor authentication method because it is simple, easy to implement, and requires no extra hardware or apps.
How SMS OTP works in brief:
- User enters username and password.
- System sends a random numeric or alphanumeric code to the user’s phone via SMS.
- User enters the code on the website or app.
- System verifies the code and grants access if it matches.
Despite its popularity, SMS OTP has some security flaws that have been well-documented over the years. For example:
- SIM swapping attacks, where hackers trick mobile carriers into transferring the victim’s phone number to a new SIM card.
- Interception of SMS messages through malware or flawed network infrastructure.
- Delays or failures in receiving SMS codes due to network issues.
What Are Passkeys and Why They Matter in 2024?
Passkeys represent a more modern approach to authentication. Instead of relying on something you know (like a password) or something you receive (like an OTP), passkeys use cryptographic keys stored securely on your device. They are part of a broader movement toward passwordless authentication, promoted by big players like Apple, Google, and Microsoft.
How passkeys work generally:
- When you register on a site, your device creates a public-private key pair.
- The public key is sent to the server, while the private key stays on your device.
- During login, the server challenges your device to prove possession of the private key.
- Your device signs the challenge and sends it back, granting access without you typing a password.
Passkeys are designed to be phishing-resistant, harder to steal, and more user-friendly once set up. They often use biometric data like fingerprints or facial recognition to unlock the private key, adding another layer of security.
SMS OTP In The Era Of Passkeys: Why Security Experts Are Talking
Despite passkeys’ advantages, SMS OTP is not going away anytime soon, which puzzles many people. Security experts discuss this ongoing relevance because:
- SMS OTP is still widely adopted by companies and users due to its familiarity.
