1Password has long been one of the most trusted password managers in the digital security world. As browser-based threats evolve, its browser extension is increasingly crucial for protecting users during everyday online interactions. But with rising malware like PylangGhost targeting browser extensions and credentials, it's worth asking: is 1Password still secure?
What does the 1Password browser extension do?
The 1Password extension simplifies password management directly in your browser. It autofills login credentials, generates strong passwords, stores 2FA codes, and manages personal info like addresses and credit card numbers—all from a single interface. It's also integrated with features like Watchtower, alerting users to breached or reused credentials.
How secure is the extension really?
1Password uses a zero-knowledge architecture with end-to-end AES-256 encryption. Only users with their Master Password and Secret Key can decrypt their data. Additionally, the browser extension runs in a sandboxed environment and communicates securely with the desktop app using verified code signatures.
Can malware like PylangGhost compromise 1Password?
Yes—but with a catch. 1Password is highly secure, but no software can protect a system that's already compromised. If a RAT like PylangGhost has taken control of your machine or browser, it can potentially access any data in memory, including credentials stored in any password manager. That's why system-level security is critical.
What's new with 1Password in 2025?
Recent updates to the browser extension include:
Full passkey support for passwordless logins.
Streamlined autofill and save prompts.
Version 2.11.0 (released June 13. 2025) includes usability and security upgrades.
Integration with AWS Secrets Manager for enterprises.
"Extended Access Management" features that go beyond MDM to secure AI and remote workforces.
Have there been any vulnerabilities?
A notable issue (CVE-2024-42219) affected earlier versions of 1Password for macOS but was quickly patched. The vulnerability allowed local attackers to impersonate the extension, proving why it's essential to keep both browser extensions and desktop apps updated.
Conclusion
1Password remains one of the most secure password managers on the market. While its browser extension is highly trusted, it's only as secure as the system it's installed on. In the era of PylangGhost and credential-stealing malware, using 1Password is just one part of a broader digital hygiene strategy that includes strong device security and cautious online behavior.
