Account Setup

Facebook accounts are the core of MessengerFlow. This guide covers adding, configuring, and maintaining accounts for optimal performance.

Adding an Account

Navigate to Accounts and click Add Account.

Required Fields

Field	Description	Requirements
Email	Facebook login email	Valid email address
Password	Facebook password	Minimum 6 characters

Optional Fields

Field	Description
2FA secret	The account's authenticator setup key, so we sign in automatically. Leave blank to sign in yourself with Live Session. See Two-factor authentication.
Proxy	Managed automatically on paid plans. On the free trial or BYO, assign one now or later; the account runs once it has a proxy.
Display Name	Friendly name for the account
Chat PIN	6-digit PIN for accounts with additional security
Cookies	Imported session cookies in JSON format

Facebook requires two-factor authentication (2FA) on accounts. For us to sign in automatically, we act as the account's authenticator: you give us the account's 2FA setup key once, and we generate the login codes from then on.

The 2FA secret is optional. If you don't have it, leave the field blank and sign in yourself with Live Session after adding the account.

Setting up 2FA and getting the secret

On the account, open Accounts Center → Password and security → Two-factor authentication → Authentication app, then Add device.
Name the device (anything) and continue.
On the "Instructions for setup" screen, copy the key shown next to the QR code (a string like 2ERG M5SF U47Q Q3JY ...). This is the 2FA secret.
Paste it into the 2FA secret field in MessengerFlow when adding the account. You'll see "Valid format" when it's right.
Back on Facebook, choose Enter code. Open the account in MessengerFlow, copy the current 2FA token (a 6-digit code that refreshes every 30 seconds), and enter it on Facebook to confirm.

That's it. We generate the login codes automatically from now on.

Already have the secret?

If your account provider gave you the 2FA setup key, paste it straight into the 2FA secret field. No need to redo the steps above.

"You can't make this change at the moment"

If Facebook blocks turning on 2FA because the account was just signed in on a new device, that is its anti-fraud check. Use the account normally for a little while (or sign in with Live Session first), then try enabling 2FA again.

Importing cookies can help with:

Faster account connection
Bypassing some verification steps
Preserving session state

Cookies must be in JSON array format:

[
  {
    "name": "c_user",
    "path": "/",
    "value": "123456789",
    "domain": ".facebook.com",
    "expiry": 1722456303,
    "secure": true,
    "httpOnly": true,
    "sameSite": "None"
  }
]

The sameSite attribute must be one of: Lax, Strict, or None.

Account Statuses

Status	Meaning	Action
Active (Green)	Account is ready to send	None required
Error	General error state	Check credentials and proxy
Invalid Credentials	Login failed	Update email/password
Invalid 2FA	2FA verification failed	Verify 2FA secret
Banned	Account suspended by Facebook	Remove or replace account
Rate Limited	Temporarily paused	Wait for cooldown period
Requires PIN	Additional verification needed	Enter chat PIN

Accounts with issues can often be resolved using a Live Session with Manual Login.

Language and Region Settings

MessengerFlow requires specific account settings:

Setting	Required Value
Language	English (US)
Region	United States
Date Format	mm/dd/yyyy

Incorrect settings will cause the account to show an ERROR status.

Changing Language Settings

Log in to Facebook
Go to Settings > Language and Region
Set language to English (US)
Set region to United States

Account Limits

All plans include unlimited Facebook accounts. You can add as many accounts as you need. On paid plans, each account that runs gets a managed dedicated residential proxy automatically.

Your subscription limits the number of active campaigns and accounts per campaign — not total accounts. See Plans & Pricing for details.

Exporting Account Data

You can export cookies and local storage data for backup:

Navigate to the Accounts page
Click the menu (three dots) next to the account
Select View Details
Download cookies or local storage in JSON format

Best Practices

Use aged accounts (created months or years ago)
Complete the profile with photos and activity
Add friends to make accounts appear authentic
Start with low message volumes and ramp up gradually
Monitor account status regularly

See the Best Practices guide for detailed safety guidelines.
