Ákos Komuves, a team member at 10log, discusses the use of FusionAuth for managing authentication needs in their suite of web-based tools aimed at the architectural acoustics and noise control industry. These tools help new and senior acousticians enhance efficiency and design quality while contributing to research in the field. FusionAuth is employed for its OAuth functionality, which facilitates user management and API protection without building a custom system. The decision to use FusionAuth was influenced by its self-hosting capability and data ownership, although it needed more than 1GB of memory to run effectively. FusionAuth's implementation has saved the company considerable time and financial resources, and it operates on a DigitalOcean droplet. With a focus on B2B applications, 10log supports a few hundred users who typically log in for extended periods. Ákos suggests improvements in FusionAuth's public GitHub repositories, highlighting some longstanding issues.
