Return to Codex to retry, switch accounts, or contact your workspace admin if access is restricted.

Here is the solution.
Vscode extension may have some issues with login in browser sometimes. you can instead install nodejs with npm if not installed.

  • Install codex with npm i -g @openai/codex.
  • Write in terminal codex login.
  • Copy that link shown in terminal into browser if it doesnt redirect.
  • Login.
  • Restart VScode and it should be working.
