Recently also Dropbox started to use the same TOTP implementation for securing with a two-factor auth. I have used the name G since they wrote the specification and at the time of this implementation, they were the only user. I wrote the application so I would be able to use 2FA on my 'aging' MeeGo phone, the N9. No tools were available and implementing it with web technologies would allow me to port it easily to a desktop environment, an extension, etc.
