Is LastPass: Free Password Manager Safe? — Extension Safety Profile

This extension requests a very broad set of permissions, including the ability to read and modify data on all websites (via host access and scripting), intercept web requests, and access cookies. These permissions are necessary for a password manager to autofill credentials, detect login forms, and sync encrypted vault data across sites, but they also grant a level of access that a careful user should only entrust to a well-audited, reputable provider.

For any password manager, the core safety consideration is that it holds the keys to your most sensitive accounts. Users should be aware that the security model depends entirely on the extension's encryption implementation and the publisher's operational integrity. Phishing campaigns often target password manager users with fake login pages or cloned extensions, so it is critical to install only from official sources and to verify the extension's authenticity.

Based on the fact sheet, the strongest dimension is Maintenance & Ownership, indicating a well-maintained codebase with recent updates. The weakest is Permissions & Access, reflecting the extensive and invasive scope of requested capabilities. The publisher has declared that data is not sold and is not used for unrelated purposes, and the extension collects personally identifiable information, authentication details, and website content — all typical for its function, but worth understanding before use.
