<![CDATA[Will upgrading FusionAuth invalidate user tokens and force re-login?]]>When planning a FusionAuth upgrade, will existing user sessions and tokens be invalidated, requiring users to log back in?

Specifically:

  • Are tokens automatically invalidated during the upgrade process?
  • Will users experience forced logouts?
  • What should be considered when planning the upgrade to minimize user impact?

However, there is one important exception: if your upgrade path includes v1.60.0, some tokens may be invalidated due to changes in token structure. The specific changes are deterministic and documented in the release notes:

Even when tokens are invalidated in v1.60.0, users with a valid refresh token should self-heal without needing to manually log in again.

Additionally, if your upgrade path includes v1.69.0, be aware of changes to key management that may require attention. Review the migration guide:

Recommendation: Review the release notes for any versions in your upgrade path to understand specific token behavior changes and plan accordingly.
