# How to send a password in Slack or Teams

> Don't paste the password itself. Put it in a temp.cool link that opens once, post the link in Slack or Teams, and the chat keeps only a dead link once your colleague has read it.

1. **Make a one-time link** Paste the password into temp.cool and set it to open once, with a timer of 1 hour or 1 day.
2. **Post the link, not the password** Send it in a direct message rather than a channel, so only one person can open it.
3. **Check it was opened** Your manage link shows when it was read. If someone else got there first, change the password.

## Why passwords in chat are a problem

- **Search finds everything.** Anyone in a channel, now or later, can search for "password".
- **Admins and exports.** Workspace admins can export messages, and compliance tools archive them.
- **Integrations read along.** Bots and apps in a channel can see what is posted there.
- **Edits and deletes don't always help.** Notifications, email digests and other devices may have kept a copy.

## Link previews won't burn it

Slack and Teams open links to build a preview. temp.cool shows a "Show the secret" button first, so the preview bot sees only that page and the secret is still there for your colleague.

## For a whole team

Need to share a login with several people? Set the link to open up to 10 times, or better, give each person their own account in the service. See also [sending a password securely](/guides/send-a-password-securely/).
