What's Wrong?

I am running claude in an SSH terminal, and I cannot paste the authentication code into the 'Paste code here' prompt. Ctrl+V (or Cmd+V) does not work. I have tried right-clicking, but it still fails.

I got around it by using this in a PowerShell window (replace your-code-here with the code from the browser, then quickly click back on the WSL terminal window):

Start-Sleep -Seconds 3; Add-Type -AssemblyName System.Windows.Forms; [System.Windows.Forms.SendKeys]::SendWait("your-code-here")

I’m also hitting this on Claude Code 2.1.105, and in my case it is not only a paste problem.

The login prompt itself gets interrupted while I am entering the auth code.

What happens:

• run /login
• start entering the auth code
• before finishing, the prompt suddenly exits with Login interrupted
• after that, the auth code ends up in the normal ❯ prompt instead of the login prompt

What I already tried:

• normal paste
• PowerShell SendKeys with the full code at once
• PowerShell SendKeys character-by-character with a short delay between characters
• sending {ENTER} separately after the code was entered

Example of what I tried in PowerShell:

• Start-Sleep -Seconds 5; Add-Type -AssemblyName System.Windows.Forms; [System.Windows.Forms.SendKeys]::SendWait("...code...")

• character-by-character:

  • Add-Type -AssemblyName System.Windows.Forms
  • $code = "...code..."
  • Start-Sleep -Seconds 5
  • foreach ($ch in $code.ToCharArray()) { [System.Windows.Forms.SendKeys]::SendWait($ch); Start-Sleep -Milliseconds 25 }
  • [System.Windows.Forms.SendKeys]::SendWait("{ENTER}")

So on my side this is not just clipboard paste failing — the login input session itself is being terminated mid-input.

Seeing the same issue here too on MacOS. Able to type in the field but cannot paste.

Seeing the same issue here too on Ubuntu.
(Linux vbm 5.15.0-173-generic #183-Ubuntu SMP Fri Mar 6 13:29:34 UTC 2026 x86_64 x86_64 x86_64 GNU/Linux)
Able to type in the field but cannot paste.

Workaround for login if your are using tmux:
tmux send-keys -t vwt-ssd:5 'claude' C-m
... some operation and url pop-up ....
... use url get the auth code ...
tmux send-keys -t vwt-ssd:5 'the auth code' C-m

Hope this helps !

Solved by rolling back to an earlier version -

curl -fsSL https://claude.ai/install.sh | bash -s 2.1.89

Also running into this. Rollback suggested by @JoshFinlayAU worked for me!
