Bitcoin Exchange Mt. Gox Adds ‘Extra Security’ With One-Time Password Card
Japan-based bitcoin exchange Mt. Gox has announced some new updates and features to its platform including a one-time password (OTP) card. — This battery-powered password generator is linked to a user's account …
Context & Ripple Effects
As of April 2013, Mt. Gox handled a confirmed 76 percent of global Bitcoin trading volume, giving any platform change it made outsized weight across the market. That same period saw the Tokyo exchange position itself as taking the lead on regulatory compliance for Bitcoin trading, so security features function partly as a trust signal to regulators as well as users.
First-order effects
- Mt. Gox users gain an offline second factor: a battery-powered card generating one-time passwords tied to their account, reducing reliance on passwords alone for logins.
Second-order effects
- With Mt. Gox holding the largest share of trading volume, its adoption of hardware OTP tokens sets a de facto security baseline that smaller bitcoin exchanges must match or explain away to win cautious customers.
Third-order effects
- If major exchanges keep layering physical second factors onto trading platforms, hardware token distribution becomes an expected cost of operating a consumer-facing bitcoin exchange — another step in exchanges absorbing bank-style security obligations ahead of formal regulation.
The trend: Bitcoin exchanges are importing traditional financial-services security practices like hardware one-time passwords to build legitimacy with users and regulators.
