- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code

### What's Wrong?

I cannot log in to my Claude account .
I am taken automatically to the let’s create your account page.
This issue has now been going on for five days and now I cannot use Claude code or connect Claude code to my console and all iOS app sessions are disconnects and cannot reconnect without log in

### Additional Information

_No response_

No source files, tests, reproducible steps, or version are identified. Start by reproducing the login flow on the reported Linux setup and determine why it redirects to account creation; done means a returning user can log in and Claude Code and existing iOS sessions can reconnect without being sent through onboarding.
