If you scored below 75%, the detailed implementation steps in the sections below will walk you through closing each security gap. Remember: hackers target the weakest accounts first. Even implementing just three or four of these measures places your account far ahead of the average user in terms of protection.
2.8 Billion X Accounts Exposed in 2025’s Biggest Data Compilation
The cybersecurity landscape shifted dramatically when researchers discovered a massive data compilation affecting 2.8 billion X user accounts in early 2025. This unprecedented incident involved a recompilation of information from multiple sources, including previously leaked data and scraped public records, rather than a direct breach of X’s systems. The compilation dwarfed previous incidents, including the 2022 exposure of 5.4 million accounts that appeared on dark web marketplaces.
What makes this compilation particularly alarming is the financial value hackers place on social media accounts. Stolen X account information commands premium pricing on cybercrime markets, with values varying based on follower count and engagement levels. This pricing reflects the strategic importance of social media accounts in modern fraud schemes, where authentic-looking profiles serve as launching pads for sophisticated scams targeting entire networks of followers.
The scale of these attacks has prompted security experts to recommend immediate action for all X users, regardless of account size or activity level. Advanced cybersecurity resources have become essential tools for understanding and implementing proper account protection strategies that go far beyond basic platform settings.
Enable Two-Factor Authentication the Right Way
Two-factor authentication stands as the most powerful defense against unauthorized account access, with research showing significant effectiveness in preventing account compromises. However, the implementation details matter significantly, especially given X’s recent changes to authentication options and the sophistication of modern attack methods.
1. Choose Authentication Apps Over SMS
X’s decision to restrict SMS-based two-factor authentication to Premium subscribers has actually improved security for most users. SMS verification remains vulnerable to SIM swapping attacks, where hackers transfer phone numbers to devices under their control. Authentication apps like Google Authenticator, Microsoft Authenticator, or Bitwarden generate time-based codes locally, eliminating cellular network vulnerabilities entirely.
Setting up app-based authentication requires navigating to Settings and Privacy → Security and Account Access → Security → Two-Factor Authentication. Choose “Authentication App” and follow the QR code setup process. This method provides superior protection against both automated attacks and targeted social engineering attempts that often succeed against SMS-based systems.
2. Save Your Backup Codes Securely
Backup codes serve as the critical safety net when primary authentication methods fail. X provides a set of single-use codes during 2FA setup that can restore account access if the authentication app becomes unavailable. These codes must be stored in a secure location separate from the device running the authentication app, such as a password manager or encrypted file.
The backup code system becomes particularly important for users who frequently travel or change devices. Without properly stored backup codes, a lost or broken phone can result in permanent account lockout, especially given X’s limited customer support response times for security issues.
3. Navigate X’s Premium-Only SMS Changes
The restriction of SMS-based 2FA to Premium subscribers represents a significant shift in X’s security model. While this change initially frustrated many users, it ultimately pushes the platform toward more secure authentication methods. Non-Premium users must now rely on authentication apps, which provide superior protection against the most common attack vectors.
For users who prefer SMS authentication, the Premium subscription offers additional security features beyond just text message codes. However, security experts consistently recommend authentication apps as the more robust solution, regardless of subscription status.
Create Bulletproof Password Protection
Password security forms the foundation of account protection, becoming even more critical as credential-stuffing attacks grow in sophistication. Modern hackers use automated tools to test millions of username-password combinations harvested from previous data breaches, making unique, complex passwords essential for survival.
4. Build 16-Character Passwords with Passphrases
The traditional approach of creating passwords with random character substitutions has become inadequate against modern cracking techniques. Instead, security experts recommend passphrase-based passwords that combine multiple unrelated words with numbers and symbols, creating 16-character minimum passwords that remain both secure and memorable.
Effective passphrases might include combinations like “RainyUmbrella47!Beach” or “CoffeeRocket23$Mountain” – long enough to resist brute-force attacks while incorporating the complexity needed to defeat dictionary-based attempts. These passwords should never be reused across multiple platforms, as a breach on one service immediately compromises all connected accounts.
5. Use a Password Manager
Password managers eliminate the human element from password creation and storage, generating truly random passwords that exceed human memory capabilities. Tools like Bitwarden, 1Password, or LastPass create unique credentials for every service while requiring users to remember only a single master password.
The password manager approach becomes particularly valuable for X users who maintain multiple accounts or frequently connect third-party applications. Each connection point represents a potential vulnerability, making unique passwords essential for containing any potential breaches to single services rather than entire account ecosystems.
Audit and Control Third-Party App Access
Third-party applications connected to X accounts create significant attack surfaces that many users overlook entirely. These applications often request extensive permissions that remain active long after users stop using the associated services, creating persistent vulnerabilities that hackers actively exploit.
6. Review Connected Applications Quarterly
Regular application audits involve accessing Settings and Privacy → Security and Account Access → Apps and Sessions → Connected Apps to review all authorized services. Many users discover dozens of forgotten applications with active permissions, ranging from abandoned social media tools to promotional services that no longer function.
The audit process should focus on removing applications with unclear purposes, extensive permissions, or long periods of inactivity. X’s API pricing changes have rendered many third-party services non-functional, yet their permissions often remain active and exploitable. A thorough quarterly review can reduce the attack surface by 80% or more for typical users.
7. Understand Read vs Write Permissions
Application permissions fall into distinct categories with dramatically different security implications. Read permissions allow apps to view posts, follow lists, and public information, while write permissions enable posting content, sending direct messages, and modifying account settings on behalf of the user.
Write permissions represent the highest risk category, as compromised applications can post spam, send malicious direct messages, or change security settings without user knowledge. The 2020 Bitcoin scam that affected 130 high-profile accounts, including those of Barack Obama and Bill Gates, demonstrated how write permissions can enable large-scale fraud operations that damage both individual users and their entire follower networks.
Turn Off Location Tracking and Data Sharing
X collects extensive location and behavioral data for advertising and analytical purposes. While this data collection enables targeted advertising, it also creates privacy risks and potential security vulnerabilities that users can control through careful settings management.
8. Disable Location Features in X Settings
Location tracking operates through multiple parallel systems within X, requiring users to disable several settings to achieve complete protection. The primary controls exist in Settings and Privacy → Privacy and Safety → Location Information, where users must turn off “Add location information to your posts,” “Personalize based on places you’ve been,” and “Personalize based on precise location.”
Historical location data presents additional risks, as this information remains attached to old posts indefinitely unless manually removed. The “Remove all location information attached to your posts” option provides a one-time cleanup of existing geolocation data, though it cannot recover information already shared with advertising partners or third-party services.
Data sharing controls require separate attention in the “Data Sharing and Personalization” section, where users should disable “Data sharing with business partners” and opt out of Grok AI training data collection. X’s updated privacy policy allows sharing user data with third-party “collaborators” for AI training purposes unless users explicitly opt out of these programs.
Recognize AI-Powered Phishing and Fake Verification Scams
Modern phishing attacks targeting X users have evolved beyond simple suspicious links to sophisticated social engineering campaigns that leverage AI-generated content and purchased verification badges. These attacks often fool even security-conscious users by mimicking legitimate platform communications with unprecedented accuracy.
The most dangerous scams in 2025 involve fake verification badge threats claiming that user checkmarks will be revoked unless immediate action is taken. Scammers purchase blue checkmarks through X Premium subscriptions and use them to impersonate customer service representatives, creating a false sense of authenticity that traditional phishing detection methods cannot identify.
High-profile cases demonstrate the evolution of these threats. Zerodha CEO Nithin Kamath’s account experienced a compromise attempt despite having two-factor authentication enabled, after he responded to a sophisticated phishing email that appeared to come from X’s security team. While 2FA prevented a full account takeover, the attack succeeded in gaining access to a single login session, highlighting both the importance of 2FA and the sophistication of modern attacks.
Protection requires understanding that X will never request passwords, verification codes, or account information through direct messages, replies, or emails. Legitimate platform communications always direct users to official settings pages through the main X interface, never through links in messages or emails. When in doubt, navigate directly to X through a browser bookmark rather than clicking any provided links.
Monitor Active Sessions for Unauthorized Access
Session monitoring provides real-time visibility into account access patterns, enabling users to detect unauthorized activity before hackers can cause significant damage. X maintains detailed logs of all active sessions, including device types, geographic locations, and login timestamps that reveal suspicious access patterns.
The session management interface exists in Settings and Privacy → Security and Account Access → Apps and Sessions → Sessions, where users can review all devices with active access to their accounts. Suspicious sessions often appear as unfamiliar device types, unexpected geographic locations, or login times that don’t match the user’s normal activity patterns.
X sends push notifications and emails about new device logins, providing immediate alerts when unauthorized access occurs. These notifications include specific details about device types and approximate locations, enabling users to quickly identify legitimate access from suspicious activity. Users should immediately revoke access for any unrecognized sessions and consider changing passwords if multiple suspicious sessions appear.
The “Log out of all other sessions” feature provides a comprehensive security reset that terminates all active sessions except the current device. This nuclear option becomes essential when users suspect widespread compromise or notice multiple suspicious sessions that suggest automated attack tools have gained access to account credentials.
Stay Skeptical – Human Error Defeats Even Perfect Settings
Technical security measures provide strong protection against automated attacks and opportunistic hackers, but human psychology remains the weakest link in any security system. Social engineering attacks succeed by exploiting trust, urgency, and authority rather than technical vulnerabilities, making skepticism the most important security skill users can develop.
The most sophisticated attacks combine technical elements with psychological manipulation, creating scenarios where users voluntarily provide access credentials or disable security features. These attacks often succeed against users with otherwise excellent security practices because they target human decision-making rather than technical systems.
Modern scammers leverage current events, platform changes, and personal information gathered from public posts to create highly personalized attack campaigns. A user who posts about traveling to Paris might receive fake security alerts claiming suspicious login attempts from French IP addresses, adding credibility to otherwise obvious phishing attempts.
The fundamental defense involves maintaining healthy skepticism about any unexpected security-related communications, especially those demanding immediate action. Legitimate security issues rarely require instant responses, and authentic platform communications provide clear verification methods through official channels rather than links in messages.
Effective security requires treating every unexpected message as potentially malicious until proven otherwise through independent verification. This approach prevents most social engineering attacks while maintaining the usability of legitimate platform features and communications.
