FusionAuth has released version 1.56.0, focusing on API security and introducing new flexibility in SSO sessions. The release includes secured storage for API keys, which are now optionally secured before being stored to reduce risks in case of a database compromise. Custom domains are also enabled for all hosting plans, allowing users to keep their domain name front and center during the authentication process. Additionally, this version enhances seamless SSO across applications, ensuring users stay logged in across multiple services without interruption. Other improvements include tackling several bugs, enhancing admin application security, improving overall system performance, and adding minor features.
