## What it is
kubelogin is a kubectl plugin (kubectl oidc-login) for Kubernetes OpenID Connect authentication, running as a client-go credential plugin. It opens a browser for login, obtains ID and refresh tokens from the OIDC provider, and passes credentials to kubectl for API access.

## Use cases
- authenticate kubectl with an OIDC provider like Google Identity Platform or Okta
- log in to Kubernetes clusters via browser-based SSO
- cache and refresh OIDC tokens for kubectl sessions
- set up client-go credential plugin authentication in kubeconfig
- replace static kubeconfig credentials with OIDC-based auth
- manage Kubernetes access for teams using an identity provider

## When to choose
- your Kubernetes API server uses OIDC authentication
- you want browser-based SSO login for kubectl
- you need token caching and refresh across kubectl invocations
- you use an identity provider like Google, Okta, or Keycloak for cluster access

## When to avoid
- your cluster uses certificates, static tokens, or cloud IAM (e.g., aws-iam-authenticator) instead of OIDC
- you need server-side OIDC proxying rather than client credential plugins
- you are not using kubectl to access the cluster
