In Multilogin, you can import saved cookie data into one or multiple browser profiles. 

➡️ Select the browser profile(s) → right-click → click “Cookies” → “Import cookies” → upload your cookie file or paste the cookie data → confirm the overwrite warning → click “Import”.

Cookie import is available to account owners, managers, and operators on all plans. Imported cookies can restore browser session data, but they don't guarantee that a website will log you in automatically.

What cookie import does

Cookies are tiny data files that websites use to remember you – like keeping you logged in or tracking your browsing habits. In Multilogin, importing cookies helps you look like a returning user instead of someone brand new. This is super useful for multi-accounting, testing, or warming up browser profiles.

With the built-in cookie import tool, you can easily upload cookie data into any browser profile – no extensions or external tools needed.

Why cookie import is useful

• Reuse saved session data: import cookies when you need to continue a browser session in a Multilogin browser profile. Some websites may still require a manual login.
• Build trust: make your profile appear more “aged” to websites

What are the limitations

To make sure your import works smoothly:

• File size must be under 100 MB
• Format must be JSON – use a JSON validator to double-check
• Browser core must be up-to-date – if the import option is missing, launch the browser profile first to update it

How to import cookies

1. Right-click a profile in your profile list
2. Click “Cookies” → “Import cookies”
   
3. In the pop-up window, either:
   1. Upload a file with cookies (JSON format), or
   2. Paste cookies as text directly
4. Tick the box “I understand that importing cookies for the same website will overwrite existing ones”
5. Click “Import” – done!
   

Pro tips

• Use cookies from trusted sources to avoid sketchy sessions
• Combine cookie import with proxies for more realistic browsing behavior
• After importing, launch the profile and visit the site to confirm cookies were applied

FAQs

What happens if I import cookies for a site that already has cookies?

The new cookies will overwrite the existing ones – so only do this if you’re okay with that!

What if my file won’t upload?

Double-check the file size (under 100 MB) and format (valid JSON). Also, make sure the profile is updated.
