[BUG] Windows: /login authorization-code prompt accepts no input (type or paste) while the main REPL composer works — interactive login impossible

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [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?

On Windows, /login opens the browser, I approve access, and Claude Code returns to the terminal asking me to paste the authorization code. That code-entry prompt
accepts no keyboard input — I can neither paste it (right-click, Ctrl+Shift+V, Ctrl+V all do nothing) nor type the characters manually. Nothing appears and nothing
can be submitted, so interactive login can never complete.
Importantly, this is not a global "stdin never reaches the process" problem: the main REPL composer accepts typing and paste normally. It is specifically the
modal authorization-code input that receives nothing — which suggests the modal text-input component uses a different input path than the main composer.
### Environment

• Claude Code: v2.1.191
• Plan / model: Claude Max, Opus 4.8 (1M context)
• OS: Windows 11, build 10.0.26200.8655
• Install method: native standalone binary (%USERPROFILE%\.local\bin\claude.exe), not the npm package — input handling can differ between the bundled-Node

binary and a system-Node npm install, so this may matter for reproduction.

• Terminals tried (identical failure in all): Windows Console Host (CMD), PowerShell, Windows Terminal.

What Should Happen?

The pasted/typed code appears in the modal prompt and can be submitted to finish login.

Steps to Reproduce

1. On Windows (native standalone binary install), run claude and trigger /login.
2. Complete the browser OAuth approval.
3. Back in the terminal, reach the "paste your authorization code" modal prompt.
4. Attempt to paste or type the code.

Additional Information

The modal prompt registers no input at all (typed or pasted); the code cannot be entered or submitted, and login cannot complete via the interactive flow.
### Scope / what was ruled out

• Multiple terminals (CMD, PowerShell, Windows Terminal) — identical behavior.
• All paste methods (right-click, Ctrl+Shift+V, Ctrl+V) and manual typing — none register.
• The main REPL composer is unaffected (typing and paste work there), so the defect is isolated to the modal authorization-code input, not the app's input handling

as a whole.
### Workaround (confirms it's input-handling, not auth)
then starts authenticated with no input required.
This is effectively permanent, not a one-shot: the credentials file contains a refreshToken (not just the short-lived accessToken), so Claude Code refreshes
silently and never returns to the broken modal. You only need to repeat it if the refresh token is revoked (explicit /logout, password change, or a revoked session).
This confirms the auth/token path itself is fine — the defect is purely that the modal code prompt never receives input.
A PowerShell helper that validates the source actually carries a refresh token (a copy without one will strand you), backs up the current creds, then installs:
```powershell
param([Parameter(Mandatory)][string]$Source)
$ErrorActionPreference = 'Stop'
$dest = Join-Path $env:USERPROFILE '.claude\.credentials.json'
New-Item -ItemType Directory -Force (Split-Path $dest) | Out-Null
$o = (Get-Content $Source -Raw | ConvertFrom-Json).claudeAiOauth
if (-not $o.refreshToken) { throw "Source has no refreshToken; it will expire and strand you." }
if (Test-Path $dest) { Copy-Item $dest "$dest.bak-$(Get-Date -f yyyyMMdd-HHmmss)" -Force }
Copy-Item $Source $dest -Force
Write-Host "Restored ($($o.subscriptionType)). Access token refreshes silently from here. Start a fresh 'claude' session." -ForegroundColor Green
Run as .\Restore-ClaudeCreds.ps1 -Source "\\path\to\known-good\.credentials.json", copying from any already-authenticated machine.
Impact
A fresh interactive /login is impossible on the affected Windows setup. Users without a second authenticated machine to copy credentials from would be fully blocked
from signing in.
