FusionAuth 1.59.0, dubbed "The Identity Ibex," introduces significant enhancements by making phone numbers a first-class identity type, thereby enabling passwordless SMS authentication. This update addresses the needs of users who either lack an email address or prefer phone-based authentication, which is particularly useful for apps targeting global markets or mobile-first experiences. Users can now register using just their phone number and authenticate with SMS codes, which reduces password fatigue and login friction. The release maintains all existing FusionAuth features like MFA and advanced threat detection for phone-based identities and includes security improvements such as cross-site scripting protection and injection attack prevention. It also features user experience and developer enhancements, such as optional passwords, JWT flexibility, and better error handling. The database schema underwent significant changes to support phone-based workflows while ensuring compatibility with existing email systems. These advancements lay the groundwork for further enhancements in mobile-first identity management, positioning FusionAuth to optimize regional SMS providers and explore additional phone-based authentication options.
