Password reuse lets attackers try a credential exposed by one service against unrelated accounts—a technique commonly called credential stuffing.
Direct answer: Password reuse lets attackers try a credential exposed by one service against unrelated accounts—a technique commonly called credential stuffing.
How reuse expands an incident
If an employee uses the same password for a vendor portal and company email, an exposure at either service can threaten both. Attackers automate these attempts at scale. Email is especially important because it often resets other accounts and contains invoices, sensitive conversations, and identity clues.

Reduce reuse without impossible memory demands
Require unique, generated passwords and provide an approved manager so employees do not have to memorize them. Protect the vault account with a strong, unique master password and MFA. Use SSO and passkeys where suitable to reduce the number of standalone passwords while maintaining recovery planning.
Respond when reuse is discovered
Identify every account that may share the credential, change the exposed passwords, revoke sessions, review MFA and recovery changes, inspect email forwarding or administrative rules, and check for suspicious activity. A password-health report can help prioritize, but confirm ownership and business impact before bulk changes.
The controls that make password management work
A vault is useful only when the surrounding operating model is clear. Start with named accounts and native delegated roles wherever a platform supports them. Keep recovery email addresses, phone numbers, billing ownership, and administrator roles under company control. Use unique credentials, require MFA on important systems, secure the devices that open the vault, and document who approves access.
When a truly shared login cannot be avoided, assign a business owner, restrict it to the smallest practical group, and record what should happen when a person changes roles or leaves. A password manager strengthens this workflow; it does not replace endpoint protection, email security, backups, monitoring, policies, or employee training.
Practical implementation checklist
- Inventory the systems your organization actually uses and assign a business owner.
- Prefer named accounts, SSO, and native delegated roles over shared master logins.
- Store unavoidable shared secrets in an approved company vault with limited group access.
- Require MFA on email, the vault, administrators, finance, remote access, and other critical systems.
- Keep recovery methods, billing, domains, and foundational administrators under company control.
- Document employee, vendor, role-change, emergency, and offboarding workflows.
- Review stale administrators, former users, exposed credentials, integrations, and exceptions.
- Test recovery and incident procedures before an urgent event.
Where NordPass may fit
NordPass is one third-party business password-management option Sun Life Tech recommends evaluating. Current provider documentation describes encrypted vaults, password generation, autosave and autofill, multi-device access, secure sharing, activity visibility, and passkey support. Business capabilities such as Shared Folders, Groups, password-health reporting, breach monitoring, or provisioning may depend on the current plan.
Verify current features, platform support, plan eligibility, data-handling requirements, and commercial terms directly with NordPass before purchase. A product decision should follow an access inventory and implementation plan—not substitute for them.

FAQ
Quick answers to common questions.
No. Predictable variants remain related and are easier to guess or recognize after exposure.
No. MFA reduces some risk but can be bypassed or unavailable; unique credentials remain important.
No. Use an approved manager, SSO, or passkeys so strong unique authentication is practical.
