Dropbox introduces U2F support for secure authentication

Dropbox is adding Universal 2nd Factor (U2F) security keys as an additional method for two-step verification to provide stronger authentication protection.

The company said the optional security keys are an easy way to use two-step verification when signing into Dropbox.

“After typing in your password, just insert your key into a USB port when you’re prompted, instead of typing in a six-digit code,” said Dropbox.

Security keys provide a stronger defence against credential theft attacks like phishing, where attackers can use fake websites to capture passwords and verification codes.

How it works

For Dropbox subscribers to use Dropbox’s U2F security keys, they will need a security key that follows an open standard called “FIDO Universal 2nd Factor” from the FIDO Alliance.

This U2F key can then be set up with their Dropbox account and any other U2F-enabled services, such as Google.

Currently, U2F is only supported for dropbox.com using the Chrome web browser.
