When a task needs you to log in, the agent is meant to hand you its computer with a “Take over” prompt so you can sign in yourself, and it didn’t surface that step here.
Two things that should help:
Ask it directly to “hand me your computer so I can log in to Claude”. That should force the takeover screen
If the login asks for a passkey or security key, choose “Try another way” (password or email code) on the login page, since passkey prompts don’t always complete on the agent’s computer.
