Chromium-based browsers store login credentials in vulnerable local databases, leaving users susceptible to credential-stealing malware that can easily bypass operating system protections to extract sensitive account information.

Key Points

• Chromium browsers store passwords in a local SQLite database that is automatically decrypted by the operating system whenever a user is logged into their desktop session.
• Credential-stealing malware, such as Lumma and RedLine, successfully extracted 1.8 billion logins globally during the first half of 2025 by exploiting this lack of application-level isolation.
• Built-in browser autofill features can inadvertently expose credentials to malicious scripts by populating hidden form fields on compromised or deceptive websites.
• Dedicated password managers like Bitwarden provide superior security by requiring a master password and utilizing AES-256 encryption that remains inaccessible to background malware.
• Users can mitigate these risks by exporting browser-stored credentials to a secure vault and disabling native browser password saving features to eliminate local vulnerabilities.

Why it Matters

Relying on browser-based password storage creates a significant security gap because the software responsible for navigating the open web also holds the keys to your digital identity. Transitioning to a dedicated, encrypted vault ensures that your credentials remain protected even if your device or browser session is compromised by malicious software.
