From ee201a5c7167a6ec4106ecd20eef62c5e7a95447 Mon Sep 17 00:00:00 2001 From: unkin-agent Date: Sat, 19 Sep 2026 15:45:01 +1000 Subject: [PATCH] Enable PKCE for ArgoCD OIDC login The Authentik client is now public (iOS app needs it), so Authentik no longer enforces client_secret. PKCE replaces that as the protection against authorization-code interception. --- clusters/au-syd1/bootstrap/argocd-cm-patch.yaml | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/clusters/au-syd1/bootstrap/argocd-cm-patch.yaml b/clusters/au-syd1/bootstrap/argocd-cm-patch.yaml index fe2f258..cfc7dc8 100644 --- a/clusters/au-syd1/bootstrap/argocd-cm-patch.yaml +++ b/clusters/au-syd1/bootstrap/argocd-cm-patch.yaml @@ -26,6 +26,10 @@ data: issuer: https://identity.unkin.net/application/o/argocd/ clientID: argocd clientSecret: $argocd-oidc:client_secret + # The Authentik client is public (the iOS app can't hold a secret), so + # Authentik no longer enforces clientSecret; PKCE replaces it as the + # protection against authorization-code interception. + enablePKCEAuthentication: true # identity.unkin.net now serves the LetsEncrypt *.unkin.net wildcard, so the # stock image trust store validates it; no rootCA pin. requestedScopes: -- 2.47.3
