Section/Topic

Credential management and OAuth token handling for Claude.ai authentication

Current Documentation

The docs currently describe refresh behavior for apiKeyHelper, but not for Claude.ai OAuth tokens:

  • Refresh intervals: by default, apiKeyHelper is called after 5 minutes or on HTTP 401 response. Set CLAUDE_CODE_API_KEY_HELPER_TTL_MS environment variable for custom refresh intervals.

  1. CLAUDE_CODE_OAUTH_TOKEN environment variable. A long-lived OAuth token generated by claude setup-token. Use this for CI pipelines and scripts where browser login isn't available.

The troubleshooting page also only tells users to log in again if a token appears expired:

If Claude Code prompts you to log in again after a session, your OAuth token may have expired.

Run /login to re-authenticate. If this happens frequently, check that your system clock is accurate, as token validation depends on correct timestamps.

What's Wrong or Missing?

Changelog v2.1.118 fixed OAuth token refresh failing when the server revokes a token before its local expiry time.

The docs do not explain that Claude Code's OAuth handling should treat the server as authoritative for token expiry/revocation and attempt refresh when the server rejects a token early. That leaves a gap for users troubleshooting unexpected auth failures, repeated login prompts, or automated environments using OAuth-based credentials.

Suggested Improvement

Add a short OAuth token lifecycle/troubleshooting subsection to authentication that explains:

  • Claude Code can refresh OAuth-backed authentication when the server reports the token is expired or revoked, even if the local expiry timestamp has not elapsed yet.
  • Server-side revocation, clock skew, or stale cached credentials can cause a token to fail before the locally stored expiry time.
  • If refresh cannot recover the session, users should re-run /login or reprovision their OAuth credentials.

Also add a cross-reference from troubleshooting back to this explanation so "token expired" guidance distinguishes between recoverable refresh scenarios and cases that truly require manual re-authentication.

Impact

Medium - Makes feature difficult to understand

Additional Context

Affected Pages:

PageContext
https://code.claude.com/docs/en/authenticationDescribes OAuth token types and credential precedence, but not server-authoritative refresh/revocation behavior
https://code.claude.com/docs/en/troubleshootingExpired-token guidance currently jumps straight to /login and clock checks
https://code.claude.com/docs/en/env-varsDocuments CLAUDE_CODE_OAUTH_REFRESH_TOKEN, CLAUDE_CODE_OAUTH_SCOPES, and CLAUDE_CODE_OAUTH_TOKEN without explaining the refresh lifecycle
https://code.claude.com/docs/en/cli-referenceDocuments claude setup-token, which links to the authentication flow affected by this gap

Total scope: 4 pages affected

Source: Changelog v2.1.118

Exact changelog entry:

extent analysis

TL;DR

Update the documentation to include OAuth token lifecycle and troubleshooting information to help users understand server-authoritative token revocation and refresh behavior.

Guidance

  • Add a new subsection to the authentication page explaining how Claude Code handles OAuth token refresh when the server reports a token as expired or revoked.
  • Include information on potential causes of token failure, such as server-side revocation, clock skew, or stale cached credentials.
  • Update the troubleshooting page to cross-reference the new subsection and provide more nuanced guidance on handling expired tokens.
  • Review and update the env-vars and cli-reference pages to ensure consistency with the new documentation.

Example

No code snippet is necessary for this issue, as it is focused on documentation updates.

Notes

The suggested improvements are based on the provided changelog entry and the affected pages listed in the issue. The updates should aim to clarify the OAuth token lifecycle and troubleshooting process for users.

Recommendation

Apply workaround: Update the documentation to include the missing information, as this will help users understand and troubleshoot OAuth token issues more effectively.
