Password Managers Extensions

Password Managers are browser extensions that connect to remote password management services such as LastPass, 1Password, and others. While they simplify access to credentials, they also risk exposing sensitive login data. 

About Password Managers

Password managers securely store and manage your login credentials, generate strong passwords, and auto-fill them for easy access. They offer enhanced security, convenience, and protection against threats like phishing and password reuse. However, like any digital tool, password managers come with risks, such as the potential for a single point of failure if the master password is lost or the manager itself is compromised.

Security Risks of Password Manager Extensions

  • Autofill on Fake Sites: Autofill can expose credentials on phishing sites
  • Credential Theft: Fake or compromised extensions may steal login data
  • Cross-Site Scripting (XSS): Vulnerable websites may expose autofilled credentials
  • Permission Abuse: Broad permissions can expose corporate accounts if misused
  • Credential Stuffing: Attackers try known user passwords on different accounts or websites, since many users reuse their passwords, leading to exposure of additional accounts
