What's Wrong?

Whenever I try to use Claude inside VSCode I get prompt to login.

So I proceed with /login ending up with page:

I see in api keys list that the key was generated. But when I get back to the VSCode Claude keeps asking me to login

What Should Happen?

Claude should login and be ready to work

I have experienced the same issue. Tried reinstalling the extension and restarting the VSCode. Nothing helped. The only thing that worked was to type / in the chat and then choose Switch Account. It provides the link to login and opens it in a browser. I believe /login should do the same.

Definitely seeing this as an issue. I had it installed and just invalidated my API token overnight and then could not see the option of login as well. Thanks @senikiti for providing a workaround . That helps!

I have same issue. I tried to use the workaround from @senikiti , it takes me to a browser window where the authentication process is completed successfully but it does not redirects to VScode or authenticate vs code.

Facing the same issue trying to login with claude.ai subscription route. Authentication is completed successfully but then nothing happens inside VSCode. Also if I copy the authentication link and generate a code myself and paste it in the login window, the screen just goes blank and nothing happens.

Tried reinstalling VSCode and the extension.

I have claude code CLI installed as well and the login works there just fine :(

I tried the workaround with Switch account of @senikiti, but it did not worked. I use Claude Code for VS Code 2.1.7 (VS Code 1.108.0) on Windows 11 Pro 21H2.

Initial steps:

• Click on "Anthropic Console"
• Open the authorization URL
• Authorize
• Redirects to: https://platform.claude.com/oauth/code/success?app=claude-code with "Build something great
  You’re all set up for Claude Code. You can now close this window"
• Chat opens and as soon as I type something I got redirected to the UI where I have to choose "Claude.ai Subscription"/"Anthropic Console" or "Bedtock, Foundry or Vertex".

At https://platform.claude.com/settings/workspaces/default/keys I see my API KEY which I created manually before. In the previous attempts I saw that new API keys are generated, but the result was the same "loop".
