The need for modern security practice in keeping passwords secure is now more important than ever after the largest password leak in history was recorded earlier this week.
According to reports, 16 billion passwords were recently leaked, affecting platforms including Apple, Facebook, Google, Telegram, GitHub, VPN services, and government portals.
This breach is believed to be the result of multiple infostealer malware campaigns operating at a massive scale throughout 2025.
The 16 billion credential leak is more than a cyber event, but an exposure to the fragility of digital identities. Access to someone’s account can lead to identity theft, hence the need for password security.
Individuals should not rely on traditional passwords alone. Adopting modern security practices is crucial against a relentless threat.
Here are ways to secure your password from hackers:
Password manager
Use a password manager to help generate and store unique, complex passwords for personal accounts. They reduce the likelihood of reusing the same password across multiple services.
Change your passwords
You can change your passwords for email accounts, bank apps, social media, cloud services, and government logins. You should also prioritise changing passwords to accounts tied to your data or finances.
Enable Multi-Factor Authentication
Multi-Factor Authentication acts as a crucial barrier which prevents access to your account. When your password is stolen, this can help act as a barrier.
Switch to Passkeys
Passkeys are a more secure authentication method that does not rely on memorised passwords and is resistant to phishing. Google and Apple are also pushing for passkeys for their users.
Monitor your accounts
You should monitor your account for any suspicious activity. Make use of tools from trusted providers to track if your password has surfaced in known breaches.
For organisations, data breach shows the need to invest in stronger cybersecurity protocols, which include endpoint protection, employee awareness training, and secure authentication systems.
