In short. Browse with Copilot can reuse a site's existing browser session through cookies, but it cannot access saved passwords or wallet information.
Definition: Yes. Microsoft documents that Browse with Copilot can access cookies in the current Microsoft Edge browser, so a site that is already signed in and accessible to Copilot can also be signed in when Copilot works there. This is reuse of browser session state through cookies, separate from access to saved passwords or wallet information.
Key facts
- Microsoft's Browse with Copilot documentation states that Copilot can access cookies and can therefore be signed in automatically to a site that is already signed in.
- Microsoft's Edge cookie documentation describes cookies as data stored by websites that can remember login credentials and says that allowing sites to save and read cookies lets them retrieve login information.
- Microsoft Learn's Edge sign-in session troubleshooting identifies blocked cookies, clear-on-close settings, and cookie policies as causes of repeated sign-in prompts.
How does the existing session reach Browse with Copilot?
Browse with Copilot works in the current Edge browser window. Microsoft says that its actions run locally in the browser and that it can work in the current tab or open another tab in the same window. The cookie rule is explicit: if the browser is already signed in to a site that Copilot can access, that site is signed in automatically when Copilot works there.
Microsoft's Edge documentation defines cookies as small pieces of data stored on the device by visited websites. It says they can remember login credentials, site preferences, and tracking information. The support page does not enumerate individual cookie names or describe site-specific authentication behavior.
What data remains outside this access?
Cookie access does not give Browse with Copilot unrestricted access to the Edge profile. Microsoft's safety documentation says that Copilot cannot access autofill data, saved passwords, or wallet information while browsing and interacting with webpages in Edge. A saved password therefore remains a separate browser data type from a cookie-backed session.
The feature also has site-level limits. Microsoft documents Edge blocklists for high-risk sites and security settings that control access to particular sites. Its support page says Browse with Copilot does not work with every site. Microsoft also advises avoiding financial activity, personal identifiers, and highly confidential data when starting agentic browsing. If a task needs personal details or payment information, Copilot asks for input and allows control of the tab so the information can be entered directly.
How can cookie reuse be checked or stopped?
Edge exposes the relevant controls under its cookie settings. Microsoft documents these paths:
edge://settings/content/cookies
Allow sites to save and read cookie data
Block
Clear on close
The Edge troubleshooting article instructs administrators and users to turn on the cookie setting and review the Block and Clear on close lists when sites ask for sign-in again. It also names DefaultCookiesSetting, CookiesBlockedForUrls, and CookiesSessionOnlyForUrls as policies that can affect persistence. For an isolated browser state, Edge provides edge://settings/profiles and an Add profile option.
To remove the session state before a Browse with Copilot task, Microsoft's Copilot documentation gives two options: delete all cookies or start with a brand-new browser profile. Edge's cookie guide says that deleting cookies for the selected time range signs the user out of most sites, and that enabling deletion on browser close removes cookies and other site data each time Edge closes.

FAQ
Will Browse with Copilot read a saved password to sign in?
No saved-password access is documented. Microsoft says that saved passwords and wallet information are outside Copilot's Edge browsing access; when a task needs personal or payment details, Copilot asks for input and the person can take control of the tab.
How can you prevent an existing sign-in from being reused?
Delete the cookies before starting the task or use a brand-new browser profile. Edge also has a setting that deletes cookies and other site data whenever the browser closes.
Does the cookie rule apply to every website?
No. Microsoft says Browse with Copilot does not work with every site, and Edge blocklists and site security settings can restrict access.
