What probably matters to youSection of the release
Profile-based credential storage keyed by ANTHROPIC_PROFILE is built, but the login screen only reaches it via a flag not visible in the bundle.
What
A new sign-in path writes an OAuth login into configs/<profile>.json plus an active_config marker under the Anthropic config directory, with the profile name taken from ANTHROPIC_PROFILE (letters, digits, underscore, dot and hyphen only). Whether it is reachable is decided by a flag the login screen is handed, whose source is not visible in the bundle, so treat it as off.
Details
It refuses, each with its own plain-English message, when: workload identity federation is configured (ANTHROPIC_FEDERATION_RULE_ID plus ANTHROPIC_ORGANIZATION_ID), the session uses Bedrock, Vertex or Foundry, ANTHROPIC_API_KEY is set, an API-key helper or injected token is in play, the profile was written by another tool, the profile has a custom credentials path, or the profile is bound to a different Anthropic deployment.
Signing out deletes the profile's credential file and can revoke the token.
None of these messages exist in 2.1.241.
Evidence
Console profile login refused: env credential shadows the profile
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
