Synchronize OTP across multiple devices
A lot of sites these days use OTP. I'm not very familiar with this, but you normally install an app like Google Authenticator on your phone. The app serves an OTP code on demand which you enter along with your user/pass into the website's login form.

For something like this, I really dislike using software from proprietary vendors. Ideally it should be something as open as possible.

Also, with many of these apps, it seems like your phone is the single point of failure. Maybe some people consider their phone very precious, but for me this is a concern - I might lose my phone, I might reinstall the OS, I don't really want to create a situation where losing access to my phone means also means losing access to my bank account.

Is there an OTP solution I can use, where my "account" can be synchronized across devices (Android, Linux PC) so that for example when a website asks me for the OTP code, I have the option of generating that from my phone as well as my computer?
