Before you start

Test Claude web chat and Claude Code separately; they can use different entitlements and authentication.

Step by step

  1. Confirm the official Claude entry point through https://support.claude.com/. Never share passwords, one-time codes or recovery keys.
  2. Review signed-in devices and third-party integrations. Remove sessions you do not recognise.
  3. Enable supported multi-factor authentication or passkeys and store recovery options securely.
  4. Redact tokens, cookies, email addresses and private file links before sharing diagnostics.
  5. Review link sharing and team permissions. An IP result does not certify anonymity or account safety.

Common questions

Can switching networks fix every Claude error?

No. Account privileges, subscriptions, file permissions and service outages require separate checks.

What should I send to support?

Share the time, client version, redacted error code and minimal reproduction. Never share a password, token, cookie or one-time code.
