How to identify user's device information?

General
1

Is there any way to identify user’s device information? Main purpose is to identify, if user is changing his/her device from last login or not. For example, I am a user “abc@test.com” and I logged in vaadin application using my android device. Next time I am using same login credentials i.e. “abc@test.com” but I logged in from My PC. If this is the case I want to send email to user that new sign in from the particular device something like gmail is giving. Thanks!!

Use

WebBrowser browser = Page.getCurrent().getWebBrowser();

And browser gives you plenty of info, see details here:

Not with plain Vaadin, that information is not available to JavaScript (and thus Vaadin). You would need an Applet or something like that.
