You can sign up for Fluxer with only a name. That account works only on one device until you add an email, and then you can sign in anywhere. - [Changing your username and tag on Fluxer](https://fluxer.com/help/usernames.md): Changing your username gives you a random four-digit tag unless you have Plutonium.
