[DOCS] Authentication docs omit `/login` support for Anthropic-operated public gateway endpoints
Documentation Type
Missing documentation (feature not documented)

Section/Topic
"Log in to Claude Code" and the gateway authentication option.
Current Documentation
The authentication page currently describes this gateway login case:
"Cloud gateway: if your organization runs a self-hosted Claude apps gateway, sign in with corporate SSO through /login. The gateway-issued token is the session's only credential."
The gateway overview likewise frames Claude apps gateway as infrastructure the reader's organization runs.
What's Wrong or Missing?
Claude Code v2.1.206 adds /login support for Anthropic-operated public gateway endpoints. The documentation only describes organization-operated, self-hosted Claude apps gateway login and does not identify the public-endpoint case.
As a result, readers cannot tell that /login can authenticate against an Anthropic-operated gateway endpoint, how that option differs from a self-hosted deployment, or what endpoint and account context they should expect during sign-in.
Suggested Improvement
Add a distinct "Anthropic-operated public gateway" login option alongside self-hosted Claude apps gateway authentication. Document:
- Who is eligible to use the public endpoints and how the endpoint is selected or supplied.
- What
/logindisplays during the browser sign-in flow. - Which credential is stored and how
/statusidentifies the active gateway. - How the public-endpoint flow differs from a self-hosted Claude apps gateway and a custom
ANTHROPIC_BASE_URLgateway.
Cross-link the gateway overview so readers choosing a gateway path can distinguish Anthropic-operated and organization-operated endpoints before following setup steps.
Impact
High - Prevents users from using a feature
