Why You Should Think Twice About Using In-Browser Password Managers

Most modern browsers—like Chrome, Edge, Safari, and Firefox—offer built-in password managers. They prompt you to save your login credentials, autofill them on future visits, and even generate strong passwords. It sounds convenient, right? But here’s the problem: convenience often comes at the cost of security.


Let’s dig into why relying on your browser’s built-in password manager might not be the safest choice—and look at better alternatives like Bitwarden, Proton Pass, and 1Password.

The Problem with In-Browser Password Managers

Browser-based password managers are designed for ease-of-use, not enterprise-grade security. While they do provide encryption and syncing across devices, they’re often deeply integrated into your browser profile—making them a prime target for attackers.


Here’s how your passwords can be stolen:

  • Malware like RedLine or Raccoon can extract browser-stored credentials in seconds.
  • Profile theft allows an attacker to clone your browser and access everything you’ve saved.
  • JavaScript injection by shady extensions or compromised websites can grab autofilled credentials.
  • Weak encryption linked to your device login means if someone gets access to your PC, your passwords are exposed.

Need Help Making the Switch?

An open-source, end-to-end encrypted password manager. Offers browser extensions, secure sharing, TOTP, and even self-hosting.

Built by the privacy-first Proton team, this manager offers advanced encryption and protects even metadata (who you log in as, where, when).

Popular with both individuals and businesses. Features include breach monitoring, secure vaults, Travel Mode, and biometrics.

Each of these tools:
  • Encrypts data before it leaves your device.
  • Never stores plaintext passwords.
  • Supports MFA and password health reports.
  • Works across browsers, phones, and operating systems.

Safer Alternatives: Use a Dedicated Password Manager

If you're currently relying on your browser's built-in password manager and aren’t sure how to disable it or migrate your data safely—you’re not alone.


Buffalo Sentinel can help you:

  • Disable password saving in Chrome, Edge, Firefox, and Safari.
  • Export your saved passwords securely.
  • Set up and configure Bitwarden, Proton Pass, or 1Password.
  • Train your team on best practices for password hygiene.


Got Infected? We’ve Got Your Back

If you ever do get infected by malware or spyware designed to steal browser-stored credentials, Buffalo Sentinel can help detect it fast.


With advanced Endpoint Detection and Response (EDR) tools and a Security Information & Event Management (SIEM) platform, we monitor for:

  • Suspicious password extraction behavior
  • Malicious command-line tools (like LaZagne or Mimikatz)
  • Unusual login patterns or data exfiltration
  • Indicators of compromise in real time
  • Early detection means faster response—and less damage.
