Hong Kong SFC Phases Out OTPs — Mandates Passkeys

How often do you use SMS or one-time password (OTP) authentication when using a crypto exchange? While it has been an annoying but necessary part of our routine, this familiar security method is now preparing to become a thing of the past.

The Hong Kong Securities and Futures Commission (SFC) recently announced it will completely phase out OTPs to combat increasingly sophisticated hacking and phishing attacks. In their place, it will introduce passkeys, which use smartphone biometric authentication, and device binding, which restricts access to authorized devices only.

Instead of entering complex passwords—long considered the standard for security—why don't we explore this convenient new era where your smartphone becomes your actual key?

Why Is Trusted OTP Being Phased Out?

The most common authentication method we use for crypto trading is an OTP received via SMS or email. You might have thought, 'This should be safe enough,' but as hacking techniques evolve rapidly, these methods can no longer guarantee your safety.

The most prominent threat is 'SIM swapping.' This is a terrifying tactic where hackers steal your personal information to activate a fake SIM card, allowing them to intercept your SMS messages in the middle. Even if you set up a complex password, the authentication code ends up directly in the hacker's hands.

On top of this, phishing via real-time fake sites is rampant. Hackers create a fake interface that looks identical to the exchange, intercepting the login credentials and OTP codes entered by the user in real time. In essence, the traditional OTP method can no longer inherently block these increasingly sophisticated hacking attacks.

What Are Passkeys and Device Binding?

Tired of entering complicated numbers every time? Passkeys have emerged as an alternative that replaces tedious code entry with simple biometric authentication, such as the fingerprint or facial recognition already registered on your smartphone. The hassle of remembering passwords will disappear entirely.

Adding to this is a robust shield called 'device binding.' Device binding literally means it will block any access from unauthorized devices, ensuring that only the specific smartphone you have designated can log in.

Using these two together makes your security far more solid. It’s as if your smartphone has become a one-of-a-kind physical key kept securely in your pocket. Even if a hacker creates a fake key, the real one remains safely in your hand, allowing you to protect your assets with peace of mind.

How Will Korean Exchanges Change?

The Hong Kong SFC's decision is not just about another country. As global financial security standards shift, we will naturally be affected as well.

In particular, with the implementation of the Virtual Asset User Protection Act in Korea, exchange security requirements are stricter than ever. In line with this, major domestic exchanges are highly likely to actively prepare for the adoption of passkeys to better safeguard their users' valuable assets.

If domestic exchanges fully adopt passkeys and device binding, we will no longer need to wait for annoying SMS messages or OTP codes every time we log in. We look forward to a future where security is much tighter while using exchanges becomes as easy and convenient as a single touch.

Tighter Security, Easier Usage

Enhanced security doesn't have to mean it becomes more cumbersome or complex. In fact, a wonderful transformation is underway where the most convenient methods—like passkeys that work with a single touch—are becoming the strongest form of security.
