How to Log Into a Facebook Account With Cookies in Dolphin Anty

How to Log Into a Facebook Account With Cookies in Dolphin Anty

Cookies are the saved session of an account. When you log in with cookies, to Facebook it continues the same session the profile lived in before you, rather than a new login from an unknown device. Together with a proxy from the right geo and the same User-Agent, it is the calmest way to open a purchased account without a checkpoint. Below is how to do it in Dolphin Anty, one of the most popular antidetect browsers among media buyers.

What you need

  • Dolphin Anty installed, with an account in it
  • The account data from your order history: login and password, email, cookies, User-Agent, and the 2FA key if there is one
  • A proxy from the geo the account lived in — a separate one for each account

Step 1. Create a profile

In Dolphin Anty click "Create profile" and give it a name you will recognise the account by. One profile, one Facebook account: open several accounts in one profile and Meta links them together.

Step 2. Set the User-Agent

In the fingerprint settings paste the User-Agent from the delivery. The browser will then present itself as the same device the account logged in from before. Dolphin Anty picks the rest of the fingerprint to match that User-Agent.

Step 3. Attach the proxy

Add the proxy to the profile and check it with the check button: the country must match the geo of the account. A proxy from another country is the most common cause of a checkpoint on the first login.

Step 4. Import the cookies

Open the cookies section of the profile and paste them from the delivery. Dolphin Anty takes cookies in JSON format — the form they are usually delivered in. Save the profile.

Step 5. Open Facebook

Start the profile and open facebook.com. If the cookies are fresh, you land in the account straight away. If Facebook asks for the password, enter it from the delivery; if it asks for a two-factor code, generate it from the 2FA key with any code generator.

The first days after login

  • Do not change the password, email or phone straight away — give the profile 1–2 days of its usual activity
  • Do not launch ads in the very first hour: the feed, reactions, a few messages — and only then the ad account
  • Always log into the account from the same Dolphin Anty profile and the same proxy

If it does not log in

Check the proxy and the geo, how fresh the cookies are, and that the User-Agent was pasted in full. If the data does not work at delivery, message support on Telegram within 24 hours with a screenshot or a recording of the login attempt, and the money goes back to your balance. You can pick an account in the Facebook accounts and farmed accounts categories.
