Secure Password Sharing: Best Practices for Teams & Individuals
Let's be honest: most of us have, at some point, sent a password in plain text through Slack, Teams, or email. We know we shouldn't, but the alternatives feel inconvenient. The problem? That password now lives in a searchable message history — forever.
In this guide, we'll cover the risks of common password-sharing methods and walk through the best practices for doing it safely.
The Worst Ways to Share Passwords
Here are the most common (and most dangerous) methods people use to share passwords:
❌ Plain text in chat (Slack, Teams, Discord)
Chat messages are stored on servers indefinitely, backed up, indexed, and searchable. If any account with access to the channel is compromised, every password ever shared in that channel is exposed.
Emails are stored in plain text on mail servers, replicated across multiple systems, and often backed up for years. They're also susceptible to forwarding — one "FW: credentials" and your password is in someone else's inbox.
❌ Shared documents (Google Docs, Notion)
A shared doc with a list of passwords might seem organized, but it creates a single point of failure. Anyone with the link (or compromised access) gets everything. Plus, document access logs and version history mean your passwords are never truly deleted.
❌ SMS / Text messages
SMS is unencrypted, readable by carriers, and susceptible to SIM-swapping attacks. It's one of the least secure channels available.
Better Approaches
✅ Password managers with sharing
Tools like 1Password, Bitwarden, and LastPass offer secure sharing features built on encrypted vaults. This is ideal for teams who need ongoing access to shared credentials.
- Credentials are encrypted at rest and in transit
- Access can be revoked at any time
- Full audit trails of who accessed what
- Role-based permissions
✅ Self-destructing notes
For one-time sharing — like sending a new hire their initial password, sharing an API key with a contractor, or passing a Wi-Fi password to a guest — self-destructing notes are perfect.
- The password is encrypted end-to-end
- The link works once, then the data is permanently deleted
- No accounts needed for either sender or recipient
- Zero data retention — nothing to breach
✅ In-person or voice communication
Sometimes the most secure channel is a phone call or walking over to someone's desk. No digital trail, no stored data. For highly sensitive credentials (root passwords, encryption keys), this remains a solid option.
Best Practices Checklist
- Never send passwords in plain text through any persistent messaging platform.
- Use a password manager for credentials that need to be accessed repeatedly by multiple people.
- Use self-destructing notes for one-time credential sharing.
- Separate the password from context — if you must share over chat, send the username in the chat and the password via a self-destructing note.
- Rotate credentials after sharing — especially for sensitive systems. Treat every shared password as temporary.
- Enable 2FA everywhere — even if a password is compromised, two-factor authentication provides a critical second line of defense.
- Use unique passwords — if one gets shared and leaked, it shouldn't unlock anything else.
- Audit your message history — search your Slack and email for messages containing "password" and delete what you find.
When Self-Destructing Notes Shine
Self-destructing notes are the ideal solution when:
- You need to share a credential once with someone
- The recipient doesn't use the same password manager as you
- You want zero data retention — no record of the password should exist after it's been received
- You need it to be fast and frictionless — no sign-ups, no app installs
Daily Noted was built specifically for this use case. End-to-end encrypted, zero-knowledge, and genuinely ephemeral. Your passwords stay yours.
