Description

The Token Trust & Traceability (TTT) working group (WG) was started in July 2023 in order to devise and formulate best practice for all aspects of the use of tokens in WLCG and related infrastructures, and inform all parties involved. From June 2025 through March 2026, the TTT WG has carried out the first-ever token usage risk assessment for routine use cases present in WLCG, EGI and OSG. The risk assessment is versioned and will be updated whenever the most recently published version is found to have become inadequate with respect to some important concern.
