(NDTV) – Bumping up the level of security for its users, Dropbox has announced U2F or Universal 2nd Factor security keys that would offer “stronger authentication protection.” The new physical security keys are USB devices that work as an additional method for two-step verification process.

Dropbox users would have to type their password while signing in the Dropbox account and then insert their key in to the USB port when prompted. This step replaces the typing of six-digit code by users. “And unlike two-step with a phone, you’ll never have to worry about your battery going dead when you use a security key,” added the company blog post. “By using cryptographic communication, they will only work when you’re signing in to the legitimate Dropbox website.”

The new security feature would require a FIDO (Fast IDentity Online) U2F-compatible USB key, which can also be used with other U2F-enabled services, such as Google services. Also added is that the new login feature for now is only available via the Chrome browser. If in case the users do not have the key handy, they would still have the option to use two-step verification process using text messages or an authenticator app.
