Blink lets you send messages in Slack that automatically disappear after a set time. Perfect for sharing passwords, API keys, tokens, or confidential data that shouldn't live in Slack history forever. Set custom expiration times (minutes, hours, or days) and messages delete automatically. Why I built this: I kept seeing teammates share credentials in Slack channels where they'd sit permanently in searchable history. Major security risk. Use /blink, and forget it.
