Yopass alternative.

Yopass is a free, open-source secret-sharing service. It encrypts your message in the browser before sending it to the server, so the server only stores ciphertext. It supports one-time viewing, expiration, and an optional passphrase for the recipient.

Who uses it: Privacy-conscious users and organizations that want to share secrets — passwords, tokens, or confidential notes — without leaving them in email or chat. It is also popular as a self-hosted tool for teams.

You enter a secret, optionally set a passphrase and expiration, and create it. The secret is encrypted client-side, and only ciphertext is sent to the server. The recipient needs the full link (with the decryption key in the URL) to read the secret, which is typically burned after a single view.

• Client-side encryption — the server stores only encrypted data.
• Open source and self-hostable.
• No account required.
• Supports one-time viewing, expiration, and passphrases.

• Text/secrets only — no file sharing.
• The decryption key travels in the URL fragment, so sharing the link insecurely weakens the protection.
• Self-hosting requires server administration.
• Public instances vary in trustworthiness and retention.

Privacy model

Strong. Yopass encrypts content in the browser (zero-knowledge) and deletes it after one view or expiration. Self-hosting gives full control over logs and retention.

Signup requirements

No account required.

Expiration behavior

Configurable — typically one-time view plus a time-to-live for unread secrets.

File & text support

Text and secrets only. Files are not supported.

Yopass and Khamli both target private, temporary text sharing. Yopass is the stronger privacy option thanks to client-side zero-knowledge encryption and one-time viewing. Khamli is simpler and broader: a managed service with a 4-character code that is easy to read aloud, file sharing up to 500 MB, and time-based expiry — but it stores plaintext server-side until deletion.

Choose Khamli when you want zero setup, need to share files or images, or prefer a short code over a long link — and don't require zero-knowledge encryption.

Yopass may be better when you need strong zero-knowledge encryption for a sensitive secret, want one-time viewing, or prefer to self-host.
