The three React components for interactive AWS credential input (access key ID, secret access key, and optional session token) were removed from the settings wizard. The SECRET_KEY and SESSION_TOKEN auth configuration constants were also removed. This aligns with the move toward OIDC Federation and profile-based authentication.
Evidence
Removed components (search for "AWS access key ID" in old version) — KaK, OsK, DsK
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
