How to Send a Password Securely?
Quick Answer
Never send passwords over email or regular chat. Use zkChat's One-Time Message feature — the password is encrypted, and the link self-destructs after one view.
Detailed Explanation
Sending passwords via email, SMS, Slack, or regular chat is a major security risk — these services store message history indefinitely. The secure approach: use a one-time, self-destructing message. Go to zkchat.org/otm, type the password, and share the generated link with the recipient. Once they open it, the password is displayed and immediately deleted from the server. The link becomes useless. The password was encrypted with AES-256-GCM the entire time, and the encryption key (in the URL fragment) never reached the server. This is the safest way to share credentials.
