JavaScript and Google Authenticator Bugs

There's nothing, not a bug in the actual UID or the spec, it's just the implementation of making sure everything matches exactly so that it's compatible with everyone else's kind ofUIDs. And then you also have to deal with state and statelessness and those kind of bugs. Like when implementing this, I kind of implemented a very kind of functional manner where you just call the function, get auid, there's no objects in state and such. But as the thing got bigger and dark changed over the years, now everyone in more object oriented kind of design.
