Vaadin 6 / 7 / 8

Hi

It is quite straightforward to implement U2F with Vaadin. You need to implement JavaScriptExtension and use yubico-java-client library. Here is an example:
https://github.com/bubblecloud/ilves/blob/master/ilves-vaadin/src/main/java/org/bubblecloud/ilves/security/U2fConnector.java

Here is a demo (you need to register and activate the U2F from your profile):

In case you do not have U2F dongle yet you can get one from Yubico:

Happy site securing :slight_smile:

Cheers,
