feat(argocd): enable OIDC token refresh via refreshTokenThreshold by Copilot · Pull Request #2026 · broersma-forslund/homelab

Copilot · 2026-02-25T08:58:40Z

ArgoCD v3.3 added background OIDC token refresh (argoproj/argo-cd#23727), preventing session timeouts when users are active but their access token expires. The helm chart 9.4.4 (appVersion: v3.3.2) already includes this feature — it just needs to be configured.

Changes

apps/cluster/argocd/values.yaml: Added refreshTokenThreshold: 5m to authentication.oidc

oidc:
  # ...
  requestedScopes: ['openid', 'profile', 'email', 'groups', 'offline_access']
  refreshTokenThreshold: 5m  # refresh when <5m remain on access token

The offline_access scope was already requested, so ArgoCD has a refresh token available. This setting activates its use.

Note: refreshTokenThreshold must be less than Authentik's configured access token lifetime. With the Authentik default of 5 minutes, consider lowering this to 2m to avoid refreshing on every request.

Pull request overview

This PR configures ArgoCD’s OIDC settings to enable background access-token refresh (available in ArgoCD v3.3.x / argo-helm chart 9.4.4), reducing the chance of user session timeouts while actively using the UI.

Changes:

Add refreshTokenThreshold: 5m to ArgoCD’s oidc.config via the chart’s authentication.oidc values.

Copilot · 2026-03-01T10:47:04Z

    clientID: $authentik-credentials:client_id
    clientSecret: $authentik-credentials:client_secret
    requestedScopes: ['openid', 'profile', 'email', 'groups', 'offline_access']
+    refreshTokenThreshold: 5m


refreshTokenThreshold needs to be strictly lower than the IdP’s access token lifetime; if Authentik is still on the common/default 5m access-token TTL, setting this to 5m will likely trigger an immediate refresh on most requests (extra load / potential rate-limits) rather than only near expiry. Consider lowering the threshold (e.g. 2m) or explicitly ensuring the Authentik access token lifetime is configured to be >5m, and documenting the constraint inline to avoid future misconfigurations.

Suggested change

refreshTokenThreshold: 5m

refreshTokenThreshold: 2m # must be strictly lower than Authentik access token TTL (5m by default)
