7 Dangers of Sharing Passwords Without a Password Manager

For individuals and enterprise teams, password sharing is a common and unavoidable practice. Done without the right tooling, it creates real exposure, like data breaches, lost credentials, and access that outlasts the people who were meant to have it.

For security and IT teams, the risk is compounded by scale. One employee sharing a credential over Slack is a minor incident that may or may not cause a bigger security issue. A workforce doing it routinely is a systematic credential risk that no audit can easily surface without centralized tooling.

Fortunately, a password manager provides a secure and convenient way to share credentials while eliminating the most dangerous sharing habits for both individuals and for enterprises.

Password sharing means giving your login credentials to others so they can access the same accounts, services, or apps you’re using. This can be done in many different ways and a variety of settings, including:

When passwords are shared through unprotected channels, every additional person or system that touches that credential becomes a potential breach point. A password sent over email passes through mail servers, inboxes, and potentially email archiving systems, any of which can be compromised.

For enterprise teams, this risk scales with headcount. A credential shared among five people across a Slack channel has five exposure surfaces. Shared across a department over a year of casual messages, it may have dozens. Dashlane's admin console gives security teams a centralized view of credential hygiene across the workforce, surfacing which employees have weak, reused, or at-risk passwords, including credentials that may have been shared through unmanaged channels and subsequently exposed in a breach.

Email, SMS, and messaging apps like Slack are not encrypted end-to-end for credential transmission. A password pasted into an email travels as readable text through multiple servers before it reaches the recipient. On public or compromised Wi-Fi networks, these messages can be intercepted in transit.

The right alternative is a channel designed specifically for credential transmission, where the password itself is never exposed as readable text to anyone, including the sender.

Dashlane's secure sharing feature transmits credentials through an encrypted channel where the recipient receives access to the credential without ever needing to see the password in plaintext. IT teams can grant and revoke that access from the admin console without requiring the original credential to be changed or reshared.

When passwords are shared informally, there's no record. Who currently has this credential? When did they receive it? Have they changed it? Is it still in their inbox? No one knows.

This matters for compliance. SOC 2, ISO 27001, and HIPAA all require demonstrable access controls, and “we emailed it to them” doesn't satisfy an auditor's request for an access log.

Dashlane's admin console maintains a record of shared credentials: Who shared what, with whom, and when. Access can be revoked instantly from the console when a project ends, a role changes, or an employee leaves, without requiring a password reset or manual coordination between teams. This makes access a controlled, auditable action rather than an informal one that disappears into message history.

Employees who are accustomed to receiving credentials over email or chat are more susceptible to phishing attacks that mimic that pattern. If your team's normal behavior includes receiving passwords in a Slack DM, a phishing message that follows the same format is harder to identify as suspicious.

Standardizing a password manager for all credential sharing breaks this attack surface. If the norm is that credentials always come through the password manager, a message asking for a credential outside that channel becomes immediately suspicious.

When an employee leaves, any credential they received through informal sharing effectively can't be revoked. You cann't delete a Slack message from their personal device or remove a password from an email they archived. If they retain access to a shared credential, they retain access to the system it unlocks indefinitely.

This is one of the most significant and underappreciated credential risks in enterprise environments, and Dashlane addresses it at the platform level. When an employee is offboarded, their access to all credentials shared through Dashlane can be revoked instantly from the admin console. The credential itself doesn't need to change.

When a password needs to be shared, employees tend to choose passwords that are simple enough to remember and type, which means shorter, less complex, and frequently reused across multiple accounts. A password designed to be communicated verbally or over chat is, by definition, not a strong password.

A password manager removes this tradeoff. The password generator creates a strong, unique credential for each account, and the sharing mechanism means the individual never needs to type, remember, or verbally communicate it to someone else.

When shared credentials live in someone's inbox or memory rather than a managed system, losing access to them causes real operational disruption. The original account holder leaves, changes the password without notifying the team, or simply forgets which version they shared, and the team is locked out of a business-critical tool until someone can reset the account.

A business password manager eliminates this category of disruption entirely. Credentials shared through Dashlane remain accessible to all authorized users, regardless of what happens to the person who originally shared them. If the sharing employee leaves, access continues for everyone else, and the admin console confirms exactly who still has it.

The alternative to informal sharing is not “don't share passwords.” Shared credentials are a legitimate operational need in any organization: team accounts, vendor logins, shared services, and departmental tools all require multiple people to have access.

The difference is how that access is granted, tracked, and removed.

This is a structural change. When Dashlane is the only supported channel for credential sharing, informal sharing doesn't happen because there's no reason for it. The managed option is faster and easier than composing a Slack message.

The biggest gap in informal sharing environments is visibility. Security teams can't manage what they can't see. Dashlane's admin console gives IT and security teams:

This is what workforce-wide credential risk visibility means in practice. It's a live dashboard that shows the current state of credential health across the organization and surfaces the highest-priority risks automatically.

The reason informal sharing persists is that it's easy. Employees choose the path of least resistance, and “paste it into Slack” is faster than any alternative that doesn't match that simplicity.

Dashlane is designed to be the path of least resistance. Employees can share credentials in fewer steps than composing a message, the recipient gets instant access without a reply thread, and the security team gets an automatic record. Policy enforcement works when the compliant behavior is also the convenient behavior.

Dashlane can be deployed company-wide in a single day and integrates with major SSO platforms so employees are onboarded with minimal friction. For new hires, day-one access to shared team credentials is handled through the admin console. No email chains, no “can someone send me the login for X.”

For security teams with existing tooling, Dashlane's credential risk signals can connect to SIEM and remediation platforms. This means:

For teams asking, “How do I connect real-time credential threat signals to my existing security stack?” this is the integration path. Dashlane feeds into the existing security workflow you already have.

The safest way to share a password is through a tool designed specifically for that purpose. A password manager's secure sharing feature:

For individuals, this replaces the habit of texting or emailing passwords. For enterprise teams, it replaces every informal channel that currently carries credentials and gives the security team the visibility and control they need to manage access at scale.

Informal password sharing remains one of the most widespread and underaddressed risks. Credentials transmitted over Slack, email, or shared documents are outside the security team's control the moment they leave the managed environment. They can't be revoked, audited, or monitored for breach exposure. At scale, this creates a long tail of uncontrolled access that persists well beyond the context in which the sharing originally happened.

It means the security team has a live view of which employees have weak, reused, or compromised credentials rather than a point-in-time snapshot from a quarterly audit. For shared credentials specifically, it means knowing who currently has access to what, and being able to act on that information instantly when circumstances change.

A business password manager with an admin console is the standard approach. Dashlane's admin console aggregates credential health data across all enrolled employees, surfaces at-risk credentials, and provides the controls to remediate them, including revoking shared access, prompting password resets, and integrating alerts into existing security workflows.

Effective remediation at scale requires three things: Automated detection (knowing when a credential is compromised without waiting for an employee to report it), centralized controls (the ability to act on compromised credentials without coordinating individually with each affected employee), and an audit trail (knowing which credentials were remediated, when, and by whom). Dashlane's dark web monitoring, admin console, and SIEM integrations address all three.

Reactive credential security responds to confirmed incidents. A breach is reported, the team resets affected passwords, and closes the ticket. The credential was already exploited before the response began. Proactive credential security surfaces risk before exploitation through credential security dashboards that flag weak or reused passwords before they appear in a breach, AI Phishing Alerts, and sharing controls that prevent credentials from entering unmanaged channels in the first place.

With a business password manager, day-one credential access is a simple admin task. The IT team grants the new employee access to the relevant shared credentials through the admin console before their first day. The employee logs into Dashlane through SSO, and their credentials are immediately available. 

Dashlane integrates with major SIEM and identity platforms, enabling security teams to route credential risk events—compromised credentials, shared passwords appearing in breach data, policy violations, and more—into their existing incident response workflows. This reduces manual monitoring overhead and ensures credential risk events are treated with the same urgency as other security signals.

The largest source of manual workload in credential risk management is informal sharing, such as tracking down who has a credential, coordinating password resets across a team, and manually auditing access when someone leaves. Replacing informal sharing with managed sharing eliminates most of that workload. Automated dark web monitoring and policy alerts handle the detection layer. Centralized admin controls handle the remediation layer. The security team moves from reactive coordination to oversight.
