U2F/Yubikey support in Opera 38+

  • Are there any plans to integrate support for Yubikeys and other U2F devices in Opera?

    Currently, this functionality is only supported in one of the major browsers – Chrome. Bringing this functionality to Opera would reduce user dependence on software-based TOTP applications like Google Authenticator, which are available on smartphone OSes and not always the best 2FA method.

    Expected behaviour

    A FIDO U2F device can be registered and used with online services as a second factor for authentication.

    Current (actual) behaviour

    Upon trying to register a Yubikey as a second factor for a Google account, a message pops up stating "Extension not installed." The registration process is interrupted.

    Other background information and resources

    Multiple online outlets, including a FAQ page on Yubico's website, mention that only Chrome supports Yubikey as of this writing.

  • Hi @julesmazur, this feature seems to be implemented ("DNA-42872 Implement FIDO U2F" - the change log) in the latest Opera developer. If you want to check it out, you can enable it as follows: after you install the developer version, go to the address bar, paste opera:flags#cryptotoken, and press Enter, select "Enabled" from the drop-down, and press "Relaunch Now".
