Guides on sharing API keys, passwords, SSH keys, documents, and other secrets without leaving a permanent trail.

Google Drive excels at long-term collaboration. One-time encrypted links minimise retention for one-off confidential handoffs. Learn when each approach fits.
Public keys are safe to share. Private keys are not. Learn when to avoid private-key handoffs, how to deliver one with a burn-after-reading encrypted link, and which PrivateNote developer extensions keep PEMs out of chat.
Email leaves permanent copies. One-time encrypted links don’t. Learn why passports, contracts, and tax files need browser encryption, expiring access, and fewer leftover copies.
Stop committing .env files, pasting tokens into pull requests, and echoing secrets in CI logs. Learn where credentials escape in GitHub and pipelines—and how one-time encrypted links fit a safer developer workflow.
Stop pasting passwords into Microsoft Teams, WhatsApp, or email. This guide shows you how to use browser-encrypted one-time links to hand off secrets safely, align with GDPR (DSGVO) requirements, and avoid critical security pitfalls.
A lock icon in a notes app is not the same as a truly private note. Learn what digital privacy actually means, which structural settings matter, and how to create an encrypted note that disappears after it is read—without ever creating an account.
Usually not. If you absolutely must, encrypt it locally first—never type the mnemonic into a website, including PrivateNote.
Email was built to deliver messages—not to make them disappear. Passwords, API keys, and recovery codes sent by email often live forever in searchable inboxes.
API keys do not belong in Slack, Teams, email, tickets, or Git history. Learn the safer workflow: scope the key, encrypt it locally, use a one-time link, and rotate it when the handoff is done.
Slack, Teams, and WhatsApp are built to preserve conversations—not protect credentials. Here are ten secrets that do not belong in chat, and the browser-encrypted, one-time alternatives PrivateNote was built for.
You do not need to sign up to share a password, recovery code, or private note securely. Learn how browser-side encryption lets you send a secret message with nothing but a link—and why that changes what a service can see.
TLS and browser-side encryption both get called "secure file sharing." They are not the same. Learn where encryption happens, why it matters, and how to choose.
Email, WhatsApp, Facebook Messenger, and Slack were built to keep messages forever. Some secrets were never meant to persist. Here's how one-time encrypted links work, when to use them, and why burn after reading is a security feature—not a gimmick.
Learn how we use cryptographic randomness, unbiased selection, and intelligent strength analysis to create secure passwords.
