  1. Detected login from an unfamiliar IP location
    → If you log in from a country or region far from your usual location, Facebook may see this as suspicious behavior.
  2. Logging in from multiple devices simultaneously
    → Frequent IP switching (via VPN, proxy, or mobile data) and simultaneous logins can trigger security flags for potential hacking.
  3. Using a bad IP address (dirty IP)
    → Your IP may be blacklisted due to past abuse—such as being used for fake accounts, spam, or hacking activity.
  4. Lack of security verification
    → Your account might not have two-factor authentication enabled, lacks ID verification, or shows minimal real activity (e.g., no friends, comments, or posts).


✅ How to Prevent and Fix This Issue​

​


1.​


  • Enable two-factor authentication (2FA) via an authenticator app (e.g., Google Authenticator or Authy).
  • Verify your identity if prompted (with government ID, passport, or driver’s license).
  • Update your profile with real info and maintain consistent activity.

2.​


  • Use clean residential proxies or high-quality VPNs that allow you to choose a consistent location.
  • Stick to a single stable IP or region; avoid switching too frequently.
  • When possible, emulate the original device and environment used during previous logins.

3.​


  • Follow Facebook’s verification steps: confirm via email/SMS, identify friends, or upload ID.
  • Avoid using fake documents — this may lead to a permanent ban.
  • After unlocking, avoid suspicious actions (like changing IP/device) for the next 72 hours.

Keep your Facebook account safe: use a strong password, enable two-factor authentication, and log in consistently from the same place. Report suspicious activity immediately.
 
Facebook may lock your profile after an IP address change to protect your account. This happens because sudden location changes, especially across countries or using VPNs, can appear suspicious or mimic hacker behavior. It’s a security measure to verify it’s really you and prevent unauthorized access.

o ensure your account is safe, you can set up Mail, personal phone number, scan Face ID or set up 2-layer security to prevent account loss.
 
This is completely normal when you buy an account from another user, Facebook is very smart and they will recognize unusual activity, you just need to verify your personal information and you can use it normally.
 
Thanks for the article! Changing IP is often easy to get blocked, especially when using poor quality proxies. You should use a stable IP, enable 2FA, update full info and create a natural activity history to reduce risks.
 
Changing your IP address frequently can easily lead to Facebook flagging and locking your account, so when logging in on different devices, you need to verify it accurately and ensure full security.
 
Facebook may delete your profile due to sudden IP Login from different countries It causes a violation of Facebook policy and leads to suspicion from which the security of the user's account Facebook will lock that account
 
Thank you for sharing very useful information. Everyone should also note when logging into any drug account or any scope of cosmetic surgery in case of emergency to close the locked account.
 
Thanks for sharing the information Facebook will block any unusual actions it recognizes so we need to be careful
 
That is the system's normal action to protect users when there is unusual activity in the account.
 
That's FB's algorithm, please note to change information after 24 hours of logging in on a new device or IP.
 
Thank you for sharing your information, it is difficult to lock your profile to ensure your account is safe.

Thanks for sharing your information very happy very happy to read your post
 
If you change your IP address frequently, Facebook will assume that your account is in danger, so it will lock your account to ensure account safety. Be careful of unusual actions that occur.
 
Facebook has a policy to protect your personal account when it sees unusual behavior occurring on your account and logging in with unfamiliar IDs is an unusual behavior that Facebook confirms.
 
In addition, we should regularly have real interactions to increase the credibility of the account (avoid overusing it or it will be counterproductive).
Things to do regularly include: posting articles with personal photos (real photos of the account owner), tagging (photos or articles) and checking in with friends, interacting (liking/commenting) on friends' posts, sending messages via messenger,...
 
Use strong passwords, enable two-factor authentication, and log in regularly from the same place. These are security measures to verify that you are really you and prevent unauthorized access.
