Hello everyone 
I'm thinking about starting a project that will utilise biometric data to log into different websites. I have a lot of passwords to a lot of websites and sometimes it's confusing to find currently needed log in data for certain website.
I was thinking about arduino-based fingerprint reader that could by plugged into PC USB port, and when visiting a website I could scan my fingerprint and by that login and password could by automatically inserted using keyboard.h libraray (from what I understood after reading description of this library - using this library the device could be seen as regular mouse or keyboard, so no extra software on PC is needed at this point).
How I see the procedure is like this:
- I'm manually entering a website that I want to log into.
- Manually go to log in section
- Scan my fingerprint.
- Arduino does it's magic and by USB port automatically insert login and passwords and enters the website.
I saw that Chromebook uses fingerprint scanning to access websites and it's something similar to what I'm trying to make, but I think it's more like second stage verification, after you log in by using login and password.
My biggest problem is that I don't know how I could pass to arduino information about which website I'm currently in. I want to make it as automated as possible, without first selecting on the device which website to use and then scan the fingerprint.
Maybe I should also use Ethernet shield and send some commands to ask PC what website is currently active?
I would like to ask you what are your thoughts about this
