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")

you are genius

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

thanks, that worked for me :)

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

Same issue on Raspberry PI OS - can't paste

Same issue on Ubuntu, unable to login

THANK YOU!

2.1.107, same problem. Rollback worked.

...but how did this ever rollout??

Same issue, it seems is globally

Why do I feel like this isn't a bug but more hostility from Anthropic against users?
I have two Pro accounts. I don't need Pro Max. Is this designed to force me to upgrade?

I tried many ideas found in the bug reports, but only this one worked for me: claude install 2.1.104

same both on MacOS, and in my debian based devcontainers. rollback is the only possible solution so far, tried every trick in the book no luck

I have Enterprise account, what exactly should I upgrade to? No, this is not hostility but a stupid bug.

The rollback to 2.1.89 solved it for me:

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

Fixed by rollback.
There should be a stable version that is a few days behind the bleeding edge version. I shouldn't have to waste time with this kind of thing. Wasted a lot of time on this.

Same issue for me, had to downgrade to 104

same issue here

If you’re running WSL, this workaround should get you sorted:

Execute these commands in your WSL terminal:

sudo apt update && sudo apt install -y wslu
echo 'export BROWSER=wslview' >> ~/.bashrc
source ~/.bashrc
claude
/login

Note: On legacy Ubuntu versions, you’ll need to run sudo add-apt-repository ppa:wslutilities/wslu before installing.

same

Same, rolling back to 104 worked

curl -fsSL https://claude.ai/install.sh | bash -s 2.1.104

same issue

same here

+1 same issue, seems to be cross-platform, can reproduce on macOS, WSL + Windows Terminal, and powershell. 2.1.89 works.

lol claude code is really becoming a joke at this point

what's even more amazing is that every time you logout you have to re-install the old version again because it automatically updates back to the broken version.

is this a bug or is this enshittification at play?

am on Arch linux and facing the same issue

Same issue here

curl -fsSL https://claude.ai/install.sh | bash -s 2.1.101

last stable version

I also found an issue, that if you try to paste back the key manually, that if the key contains n, it will immediately cancel the login (even typing a single n in the prompt will cancel it)

I was able to rollback using claude codes build in installer

# 1. Roll back to stable
claude install stable

# 2. Log in like usual with /login

# 3. Go back to latest
claude install latest

Running Ubuntu 24.04 in a docker container. Pasting was broken. Rolling back to 2.1.101 fixed my problem.

npm install -g @anthropic-ai/claude-code@2.1.101

Same issue here on MacOS

Same issues in wsl. Can't paste. Tyring to type the code, got interrupted.

Same issue in x86 linux

I also found an issue, that if you try to paste back the key manually, that if the key contains n, it will immediately cancel the login (even typing a single n in the prompt will cancel it)

if you can confirm this, absolutely open a bug ticket for it, and not leave here as a comment cause they will never know about it.

I used this and it works

This is a ridiculous bug, but it seems (at least on Windows) I was able to get this to work by copying the code, going back to the HA window, clicking to focus, just to be sure, and then using ctrl+shift+v to paste

Try shift+insert instead of strg+v! worked for me

BTW: Claude Chat found the way: Echte Lösung: Der Login-Flow erzeugt eine URL. Du öffnest sie im Browser, bekommst den Code — und kannst ihn direkt per WSL-Clipboard reinschreiben:
bash# In WSL, wenn du beim Code-Prompt bist:

Einfach den Code in die WSL-Zwischenablage legen und mit Shift+Insert einfügen

Shift+Insert statt Ctrl+V — das ist der klassische Linux-Paste-Shortcut im Terminal. Hast du das schon probiert?

This is a duplicate of #47699, which was fixed as of version 2.1.108.

What? You’re closing it as a duplicate of itself?
