Is Keeper® Password Manager & Digital Vault safe?

Keeper Password Manager stores, autofills, and manages credentials across all websites and supports enterprise SSO authentication.

The extension injects into every page to detect login forms and offer autofill from the user's encrypted Keeper vault. For enterprise users, it registers an SSO content script on all URLs that listens for postMessage events without validating the sender's origin, meaning any page could send a message to trigger SSO login flows. Credential data is transmitted to Keeper Security's servers at keepersecurity.com for authentication and vault sync.
