Analysis of Claude Code Third-Party API Authentication Conflict Issues

Recently, users have reported encountering authentication conflict issues when using Claude Code. After installing Claude Code and the cc-switch tool via Homebrew on Mac, users attempted to configure third-party API keys, but still needed to log in to their Anthropic account when opening Claude Code. After logging in, an authentication conflict prompt appeared. Although this doesn’t affect basic functionality, it results in a poor user experience. Users tried using the /logout command to exit their Anthropic account, but when reopening Claude Code, they were required to log in again. Currently, this issue has not been effectively resolved, and related discussions are still ongoing. This situation serves as a valuable reference for users who rely on Claude Code and third-party APIs, and also provides developers with potential directions for problem feedback.
