225225Claude Code checks three sources in this order and stops at the first one that is set. The table shows what sets each source and where it ranks against your `/login` credential.

227| Source | Set by | Rank against `/login` |
228| :------------------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :-------------------------------------------------------------------------------------------------------------------- |
229| Named profile | `ANTHROPIC_PROFILE` | Above, whichever auth mode the profile has |
230| Federation variables | `ANTHROPIC_FEDERATION_RULE_ID` and `ANTHROPIC_ORGANIZATION_ID`, both set | Above |
231| Active profile | The [`active_config` file](https://platform.claude.com/docs/en/manage-claude/wif-reference#active-profile) in your configuration directory, or a profile named `default` | Above when its auth mode is `oidc_federation`; below a working `/login` credential when its auth mode is `user_oauth` |

233233The `user_oauth` rule keeps a leftover `ant auth login` profile from moving your requests off the account you signed in to with `/login`. For the federation variables, Claude Code also reads the other variables in the [WIF reference](https://platform.claude.com/docs/en/manage-claude/wif-reference#environment-variables), such as `ANTHROPIC_IDENTITY_TOKEN_FILE`, when it exchanges your identity token. For the profile file format, see the [WIF reference](https://platform.claude.com/docs/en/manage-claude/wif-reference#profile-configuration-file).
