TL;DR: Browsers make password saving and sync easy, but that convenience pushes business credentials into places IT cannot reliably audit, share, or revoke, according to 1Password’s analysis. Browser-based storage turns credential management into a governance problem, not a user preference, because access now lives across profiles, devices, and offboarding gaps.
NHIMG editorial — based on content published by 1Password: browser password managers create security and governance blind spots for business credentials
By the numbers:
- 38% of employees have successfully accessed a prior employer’s account.
- 36% of American workers have clicked on a suspicious email at work.
Questions worth separating out
Q: How should security teams stop business credentials from living in browser password managers?
A: Security teams should move business credentials into a governed vault with shared access controls, logging, and lifecycle management.
Q: Why do browser-saved passwords create more risk than they appear to?
A: Browser-saved passwords create more risk because they spread across profiles, devices, and sync services without a single authoritative control plane.
Q: What breaks when employees use browser sync for work credentials?
A: When employees use browser sync for work credentials, offboarding and incident response become uncertain because copies can persist on multiple devices and profiles.
Practitioner guidance
- Move business credentials out of browsers Use a dedicated credential manager for shared secrets, team vaults, and privileged logins so access is governed centrally instead of scattered across browser profiles and sync services.
- Treat browser sync as an audit scope Include browser-saved credentials and synced profiles in access reviews, offboarding checks, and incident response runbooks so hidden copies do not survive role changes or exits.
- Restrict extension permissions by default Review browser extensions as part of the credential attack surface, and block add-ons that can read page content, modify forms, or intercept sensitive authentication flows.

Browser-based password storage is a governance failure, not a user convenience choice. When business credentials sit in consumer browsers, the identity team loses control over storage location, sharing method, and revocation path. That breaks the basic assumption that credentials live in a managed system with enforceable policy. The implication is that browser storage should be treated as shadow credential handling, not as an acceptable enterprise default.
A few things that frame the scale:
- 38% of employees have successfully accessed a prior employer’s account, according to The State of Non-Human Identity Security.
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, with 38% having no or low visibility and 47% only partial visibility.
A question worth separating out:
Q: How should teams reduce extension risk when the browser also holds credentials?
A: Teams should limit extension permissions, review installed add-ons as part of the attack surface, and remove business credentials from the browser wherever possible. If the browser contains the credential and the extension can read or alter the page, the trust boundary is already too wide. Reduce the browser’s access before relying on it for login.
