Why do I need to collect cookies?

Cookies store website session data, preferences, and browsing state inside a Multilogin browser profile. Keeping this data in the same profile can help maintain a consistent session over time. Cookies do not guarantee that a website will trust an account or prevent restrictions.

Can websites see cookies from other websites?

Not really. Thanks to the same-origin policy, websites can’t peek into cookies from other domains. For example, BBC.com won’t see cookies from Etsy.com.

However, some tracking tools can collect data across multiple sites. For example:

• Facebook pixels (like those "Like" or "Share" buttons) drop a unique cookie on your browser – later, Facebook reads this cookie to track your activity across different websites
• Google Analytics does something similar through embedded tracking scripts

So, while individual sites can’t share cookies, big platforms with tracking tools can.

Does cookie age matter?

Yes! The older, the better (well, to an extent). If you're collecting cookies, let them sit for a few days before using them on a target website. This helps build a believable browsing history, making you look like a real user rather than a fresh bot.

Can I collect cookies without a proxy and use them later with a different IP?

It might seem like a good idea to collect cookies without a proxy and only use one when you create an account, but it’s not recommended. Cookies can store your location (like your IP address), so if you collect cookies in one place (e.g., Brazil) and then use them later with a different IP (e.g., in the UK), the website might notice the switch and flag it.
