Claude Code Login Failures: Active Incident Report
Anthropic’s Claude Code CLI tool is currently experiencing elevated authentication failures. Users attempting to initiate new sessions may be unable to log in. The incident is tracked at Anthropic’s public status page [1].
As of this writing, no resolution timeline has been posted.
Impact
Claude Code operates as a terminal-resident coding agent â login is required before any interaction. Unlike the web-based Claude interface, there is no fallback UI. If authentication is down, the tool is effectively unavailable.
Teams that have integrated Claude Code into CI pipelines or developer workflows should verify whether existing authenticated sessions remain functional or whether only new login attempts are affected.
Practical Notes
| Scenario | Likely Status |
|---|---|
| Already authenticated session | May continue working |
| New login attempt | Elevated failure rate |
| API calls via existing tokens | Unconfirmed; check status page |
If you are currently blocked:
- Monitor status.claude.com for updates.
- Existing sessions may still function â avoid logging out.
- Consider switching to the web interface for non-CLI tasks in the interim.
Context
This is a service-level authentication incident, not a capability or model issue. Claude Code has had periodic availability events since its launch, which is typical for developer tooling in active development. Anthropic’s status page provides the canonical source for resolution updates.
