"Hey, what's the login for the company Instagram?"
"One sec, I'll DM it to you on Slack."
This exchange happens thousands of times a day in small businesses around the world. It seems harmless. It's convenient. Everyone's already on Slack anyway.
But here's the uncomfortable truth: Every time you share a password over Slack, you're creating a potential security disaster.
## Why Slack Wasn't Built for Password Sharing
Slack is an amazing tool for team communication. But it was never designed to be a secure credential vault. Here's what happens when you share passwords there:
### 1. Messages Are Permanently Searchable
That password you shared six months ago? It's still sitting in Slack's search history. Anyone with access to that channel can find it instantly.
Even in direct messages, those credentials live forever in the search index. If someone's account gets compromised, the attacker has access to every password ever shared.
### 2. No Way to Revoke Access
Let's say an employee leaves your company. You revoke their Slack access. Great.
But they already have screenshots of passwords on their phone. They've copied credentials to their personal password manager. You have no way to know which passwords they saw or to automatically revoke their access.
### 3. Slack Gets Hacked (Yes, Even Slack)
In 2022, Slack experienced a security breach. In 2023, it happened again. No platform is immune.
If an attacker gains access to your Slack workspace, they don't just get your conversations—they get every login credential your team has ever shared.
### 4. Third-Party Integrations Are Wildly Insecure
That Slack bot you installed to track GitHub commits? It has read access to all your channels. The Zoom integration? Same thing.
Every third-party app with Slack access can potentially read messages containing passwords. You probably have no idea how many apps have this level of access.
### 5. Mobile Notifications Expose Passwords
"John shared a password with you: hunter2"
This notification pops up on someone's phone while they're on the subway. The person standing next to them just saw it. Now they have your password.
Lock screen notifications are a massive security hole that people rarely think about.
## The Real-World Consequences
"This would never happen to us" is what every business thinks—until it does.
Here are real scenarios that happen to small businesses every week:
**Scenario 1: The Contractor Who Didn't Leave**
You hire a contractor for a 3-month project. They get access to Slack. They see passwords shared in team channels. The project ends. They still have all those credentials.
**Scenario 2: The Accidental Public Message**
Someone means to send a password in a DM. They accidentally post it in #general. 47 people see it before they can delete it. Too late.
**Scenario 3: The Phishing Attack**
An employee's Slack gets phished. The attacker now has access to every password conversation in that employee's message history. You don't find out for three weeks.
**Scenario 4: The Screenshot Disaster**
An employee screenshots a Slack conversation containing passwords for "reference." That screenshot syncs to their personal iCloud. Their iCloud gets hacked. Your business credentials are now on the dark web.
## What Your Team Is Probably Doing Right Now
Based on research and countless small business interviews, here's the password chaos that's likely happening:
- Some team members save passwords in their browser
- Others write them in a notebook
- A few use personal password managers (1Password, LastPass)
- Some keep a Google Sheet with "important logins"
- Passwords are shared via Slack, email, text message, or Post-It notes
The average small team manages 147 different passwords. With no consistent system, it's pure chaos.
## The Right Way to Share Passwords
The solution isn't to stop sharing passwords. Collaboration requires shared access. The solution is to share them *securely*.
### What Good Password Management Looks Like
**1. Encrypted Storage**
Passwords are stored with end-to-end encryption. Even if the service gets hacked, encrypted passwords are useless without the decryption key.
**2. Granular Access Control**
You can control who sees which passwords. Marketing team sees social media logins. Dev team sees API keys. Finance sees bank account access.
**3. Easy Revocation**
When someone leaves, you click one button and they lose access to all shared passwords. No scrambling to figure out what they had access to.
**4. Audit Trail**
You can see who accessed which password and when. If something goes wrong, you know exactly where to look.
**5. Secure Sharing**
Team members can access shared passwords without them ever appearing in chat messages, screenshots, or notifications.
### Options for Small Teams
You don't need enterprise-level security. You just need something better than Slack messages.
**Option 1: Dedicated Password Managers**
Tools like 1Password for Teams or LastPass Business are built specifically for this. Cost: $4-7 per user/month.
**Pros:** Designed for password security
**Cons:** Yet another tool to manage and pay for
**Option 2: All-in-One Business Tools**
Some business management platforms include secure password sharing as part of a broader toolkit.
**Pros:** One tool for multiple needs (passwords + files + tasks)
**Cons:** Make sure the password feature has proper encryption
**Option 3: Self-Hosted Solutions**
For the technically inclined, tools like Bitwarden can be self-hosted.
**Pros:** Complete control over your data
**Cons:** Requires technical expertise to set up and maintain
## Take Action This Week
If you're currently sharing passwords over Slack, here's your action plan:
**Day 1:** Acknowledge the problem
Admit that your current system is a security risk. This isn't about blame; it's about fixing it.
**Day 2:** Pick a solution
Choose a proper password management system. Don't overthink it. Even a basic solution is infinitely better than Slack.
**Day 3:** Migrate critical passwords
Move your 10-20 most important credentials first. Bank logins, domain registrar, company social media, payment processors.
**Day 4:** Train your team
Show everyone how to use the new system. Make it easier than Slack so they'll actually use it.
**Day 5:** Set a no-Slack-passwords rule
Announce: "From now on, all password sharing happens in [chosen tool]. Zero exceptions."
**Week 2:** Change the most-shared passwords
If passwords were shared via Slack before, assume they're compromised. Change them.
## The Peace of Mind Is Worth It
Yes, changing your password management system is a hassle. You're busy. You have actual work to do.
But here's what you get in return:
- Sleep better knowing your credentials aren't sitting in Slack history
- Stop worrying when employees leave
- Spend zero time explaining "what was the password for X again?"
- Avoid the nightmare scenario of getting hacked
Your business is too valuable to protect with Slack DMs and Google Sheets.
