Quick answer: The safest simple way to share a Wi-Fi password is to avoid permanent group chats and use a one-time note link. For guests or contractors, use a guest network and rotate the password after access is no longer needed.

Do this, not that
- Avoid: posting the Wi‑Fi password in group chat or email.
- Prefer: a one‑time link that self‑destructs after being read.
