Sharing passwords is often necessary, but doing it wrong can lead to serious security breaches. In this guide, we cover the only safe way to share credentials.
The problem with how we usually share passwords
When you send a password over email, Slack, or Microsoft Teams, that password is saved in the chat history forever. If anyone ever hacks that email inbox or slack account, they gain access to all those passwords.
Even worse, chat logs are often backed up to the cloud without end-to-end encryption, exposing your credentials to third-party servers.
Best practices for sharing passwords
1. Never send passwords in plain text
Always use a secure medium to transmit the actual characters of the password.
2. Use burn-after-reading links
A self-destructing link ensures the password can only be viewed once. If a hacker intercepts the link later, it will already be destroyed.
3. Separate the username and password
Send the username via Slack, and send the PassLink with the password via email. This split-knowledge approach adds a layer of defense.
