Why You Should Never Share Passwords in Work Chat (And What to Do Instead)

"I'll just Slack you the password." It sounds harmless, but sharing passwords through work messengers like Slack, Microsoft Teams, or iMessage is one of the most common — and most dangerous — security shortcuts in business.

Here's why it's risky and what you should do instead.

Why Sharing Passwords in Chat Is Dangerous

Reason 1: Messages Live Forever

Unless manually deleted, chat messages persist indefinitely in most platforms.

Risk	Detail
Former employees	Can access message history if account isn't deactivated
Account compromise	Attacker gains access to entire chat history
Device loss	Lost phone or laptop exposes all chat data
Screenshots	No way to prevent message capture

Reason 2: Wrong Chat, Wrong People

Accidentally sending a password to a group channel instead of a DM happens more often than you'd think.

• Password visible to unintended recipients
• External partners in shared channels can see it
• Message recall doesn't guarantee no one saw it

Reason 3: Admin Visibility

On enterprise plans, administrators can export all messages — including your DMs. This means:

• IT admins may have access to passwords you shared
• Compliance audits can surface password messages
• Legal holds can expose sensitive messages

Reason 4: Search Makes Passwords Easy to Find

Search for "password," "login," or "credentials" in your work chat. Chances are you'll find passwords shared months or years ago, still sitting there in plain text.

Safe Ways to Share Passwords at Work

Method 1: Password-Protected Links

Instead of typing passwords directly into chat, share them through encrypted, time-limited links.

With LOCK.PUB's secret memo feature:

1. Create an encrypted memo with the password or credentials
2. A password-protected link is generated
3. Share only the link in Slack or Teams
4. Recipient enters the password to view the memo
5. After expiration, access is automatically revoked

Benefits:

• No password text in chat history
• Configurable expiration
• Access logs show who viewed it
• End-to-end encryption

Method 2: Password Manager Sharing

1Password, LastPass, Bitwarden, and similar tools have secure sharing features built for teams.

• Encrypted sharing
• Access permission management
• Password changes sync instantly

Method 3: Temporary Passwords

Instead of sharing, issue a temporary password and require immediate change.

1. Set a temporary password
2. Share via chat (it's temporary, so lower risk)
3. User logs in and changes password immediately
4. Temporary password is now invalid

What You Should Never Do

Bad Practice	Risk
Send password directly in chat	Stays in history permanently
Store passwords in a shared spreadsheet	Everyone with access can see them
Send username and password in the same message	Both leak together
Pin a message containing credentials	Maximum exposure
Use the same password across shared accounts	One leak compromises everything

Harden Your Work Chat Security

Enable Two-Factor Authentication

Mandate 2FA for all team members on every chat platform.

Regular Member Audits

• Deactivate accounts immediately when employees leave
• Remove unnecessary external members regularly
• Minimize admin privileges

File Sharing Policies

• Never upload files containing passwords
• Share sensitive files through time-limited, encrypted methods

Secure Password Sharing by Scenario

Scenario	Recommended Method
New employee system access	Password manager or temporary password
External partner access	LOCK.PUB secret memo with expiration
Wi-Fi password sharing	LOCK.PUB password-protected link
Shared account handover	Password manager
Emergency password delivery	Phone call + LOCK.PUB link

The Bottom Line

Work chat is great for communication, but it's the wrong place for passwords and credentials. Chat history is permanent, searchable, and accessible to more people than you think.

Rules for safe password sharing:

• Never type passwords directly in chat
• Use password-protected links or encrypted memos
• Always set an expiration
• Change passwords after sharing
• Mandate 2FA for everyone
