Hong Kong’s Securities and Futures Commission has ordered crypto trading platforms and online brokers to phase out one-time password logins, mandating a shift to phishing-resistant authentication methods for regulated firms.
What the SFC Ordered on OTP Logins
The SFC issued the directive targeting two categories of regulated entities: licensed virtual asset trading platforms and online securities brokers. The regulator’s announcement frames the measure as a compliance requirement rather than a voluntary cybersecurity recommendation.

The order calls for a phase-out of OTP logins, giving covered firms a transition window rather than imposing an immediate cutoff. Both crypto-native platforms, such as those on the SFC’s list of licensed virtual asset trading platforms, and conventional online brokers fall within the directive’s scope.

The move comes as Hong Kong continues to build its regulatory framework for digital assets, including recent steps like facilitating Hong Kong-regulated fiat tokens reaching Ethereum’s mainnet.
Why the SFC Is Moving Firms Away From OTP Authentication
The regulator’s rationale centers on the known security weaknesses of OTP-based login systems. One-time passwords delivered via SMS or email are vulnerable to SIM-swapping attacks, phishing interception, and man-in-the-middle exploits that can compromise client accounts.
The SFC has mandated phishing-resistant authentication methods as the replacement standard. Phishing-resistant methods typically include hardware security keys, biometric authentication, or passkeys that bind credentials to a specific device, making them far harder to intercept remotely.
For crypto platforms in particular, where account compromises can result in irreversible fund losses, the upgrade carries direct investor-protection implications. Unlike traditional brokerage accounts where fraudulent transactions can sometimes be reversed, stolen digital assets are generally unrecoverable.
What the Order Means for Crypto Platforms and Online Brokers
Regulated firms will need to overhaul their client-facing login infrastructure. This includes deploying new authentication backends, updating mobile and web applications, and guiding existing users through credential migration, all within the SFC’s transition timeline.
For users of affected platforms, the most visible change will be the login experience itself. Clients should expect prompts to register hardware keys, enable biometric login, or set up passkey-based access in place of the familiar SMS or email code entry.
The compliance burden falls broadly. Hong Kong’s SFC oversees both crypto-native operators and traditional brokers offering online trading, meaning the operational impact spans firms of varying sizes and technical maturity. Smaller operators may face disproportionate implementation costs compared to larger exchanges that have already adopted multi-factor or passwordless login flows.
The authentication directive fits within Hong Kong’s broader push to tighten standards across its regulated digital-asset market. As other jurisdictions, including Japan’s ruling party pushing for crypto ETFs and stablecoin frameworks, pursue their own regulatory strategies, Hong Kong is signaling that operational security standards for licensed platforms are as much a priority as market-access rules. Regulators globally are also weighing how actively to shape crypto oversight, and Hong Kong’s prescriptive approach to authentication offers one model for that effort.
