ChatGPT can now log into your accounts for you. Here's the trade-off.

ChatGPT's agentic Work mode now signs into password-protected websites once and stays signed in for future tasks, using cookies stored in its built-in cloud browser rather than your own. The mechanism matches any normal browser session; the difference is where the session lives.

Per OpenAI's release notes, a first task that requires a login prompts the user for a username and password, manually or via a third-party password manager. After that, the agent replays the stored session cookie and skips the prompt, the way Chrome autofills a saved login on a return visit. The feature is gated to ChatGPT Pro and ChatGPT Plus subscribers.

A ZDNET hands-on test asked ChatGPT Work to sign in and list the items and prices on the reviewer's public Amazon wish list. The first run asked for credentials; subsequent runs signed in without prompting. The reviewer also hit hiccups pushing beyond the wish-list test, suggesting the feature works for narrow tasks with rougher edges elsewhere.

OpenAI's stated use cases include checking utility plans for a new apartment, booking a DMV appointment, looking up insurance prices for an X-ray or bloodwork, and finding recruiters' open-to-work profiles. The grant only covers sites the user has already signed into through ChatGPT's browser, and it can be revoked there.
