16 Billion Passwords Leaked: How to Protect Your Accounts Now

What Happened

In June 2025, cybersecurity researchers discovered 30 exposed datasets containing over 16 billion login credentials. These records included usernames, passwords, and login URLs linked to widely used platforms such as Apple, Google, Meta (Facebook/Instagram), GitHub, Telegram, and even government portals. Importantly, this massive exposure wasn’t the result of a breach within those companies. Instead, the credentials were harvested by "infostealer" malware that quietly infects devices and captures sensitive login information as users go about their day.

According to Cybernews, approximately 85% of this data is tied to recent infections, underscoring the continued activity and danger posed by these threats. Experts are calling it one of the largest credential leaks in history, with serious implications for both individuals and organizations, including the risk of phishing attacks, account takeovers, and identity theft.

What You Should Do Now

If you haven't already, the first step is to change any reused passwords, especially on high-value accounts like those with Apple, Google, or Meta. Using the same password across multiple accounts leaves you vulnerable to credential-stuffing attacks. Each of your accounts should have its own strong, unique password.

Next, enable Multi-Factor Authentication (MFA) wherever it's available. MFA adds a critical second layer of defense, and tools like Duo Security make it easy to secure your accounts using an app-based prompt or hardware token. MFA ensures that even if someone steals your password, they can’t access your account without the second authentication factor.

It’s also important to regularly scan your devices for malware. Many infostealers operate quietly in the background, so you may not realize your credentials are being siphoned off. Reliable antivirus or anti-malware tools can help detect and remove these threats.

You should also consider using passkeys, which are an emerging technology designed to eliminate the need for passwords altogether. Built into platforms like Apple and Google, passkeys are resistant to phishing and make credential theft nearly impossible.

Finally, it’s a good idea to monitor whether your credentials have already been exposed. Tools like "Have I Been Pwned" can alert you if your information has shown up in known breaches, giving you a head start in protecting your digital identity.
