Every username generator tool contains different options and requirements to create a name, but most involve clicking a button to generate a name following some set of guidelines, such as a theme or character length. Some allow you to enter custom fields to incorporate certain elements into the name, while others automatically draw from a database of terms to provide a username.
Username generators are a form of a name generator tool that focuses on creating names suitable for use in online credentials rather than mirroring the names of a specific region, theme or aspect of popular culture. As such, the tools often feature some customization features that allow you to incorporate details about yourself and your personality in the name. After you enter these terms, the tool pairs them with terms from its database to provide you with usernames for a variety of contexts.
For example, the username generator at Spinxo.com allows you to enter a nickname, number, hobby, interest or adjective to use as an element of the final username. By entering the terms and clicking the Spin button, you receive 30 sample usernames that incorporate one or more of the terms along with other words or word fragments. Some username generators only allow for a single term as part of its generation process, but the general process of clicking a button to view different options is the same. Most username generators draw from common nouns and adjectives, but some may also use names or historical terms.
