Password sharing is a reality of modern business. Agencies share marketing logins with clients, IT shares temporary device passwords with new hires, and developers share database credentials. But doing it securely is critical.
The Wrong Ways to Share a Password
1. Slack or Microsoft Teams
Enterprise chat apps index everything. A password sent via Slack is searchable by workspace admins forever. If a former employee’s session token is stolen, hackers often just search "password" in Slack and hit the jackpot.
2. Email
Emails bounce through multiple servers, are rarely scanned for PII leaving the network, and lay dormant in thousands of sent folders.
The Right Way: Burn-After-Reading Links
The most secure way to share a credential is out-of-band using an encrypted, ephemeral link.
Tools like PassLink encrypt the password on your computer. You send the resulting link via Slack or Email. When the recipient clicks it, the password decrypts in their browser and the encrypted payload is instantly deleted from the server. There is no history, no searchable archive, and no risk of future exposure.
Corporate Best Practices
- Separate the username and password. Send the URL/username via email, and the password via an encrypted PassLink.
- Use short expiration times. If your client doesn't open the link within 24 hours, let it expire.
- Add password protection to the link itself if you are sending via an insecure channel.
