We’re thrilled to introduce the Limited Early Access release of Additional Signing Algorithm for Okta and OIDC enterprise connections! This release expands flexibility for both Private Key JWT client authentication and ID token verification by adding support for stronger signing algorithms beyond RS256, including:
For Private Key JWT, Auth0 now lets you choose which algorithm is used to sign client assertion JWTs when authenticating requests to an upstream IdP. For ID token verification, Auth0 can validate tokens signed with a wider set of algorithms, ensuring compatibility across OIDC flows. Together, these enhancements give customers more control over cryptographic choices, making it easier to align with security policies and adapt as standards evolve
This release is currently rolling out to all environments. To enable the Additional Signing Algorithms Limited Early Access release in your Auth0 tenant once available in your environment, please contact your Technical Account Manager to request access.
