How OneTimeSecret Works
Share passwords, API keys, and confidential messages securely in three simple steps. No signup, no software, no complexity.
Enter Your Secret
Navigate to OneTimeSecret and paste any sensitive text into the secure input field. This can be a password, an API key, SSH credentials, a private message, database connection strings, or any confidential data you need to share.
Get Your Encrypted Link
OneTimeSecret immediately encrypts your data using AES-256 encryption and generates a unique, one-time link. This link contains a cryptographic token that maps to your encrypted secret on our servers. The encryption key is embedded in the link itself, so our servers never store the key alongside your data.
Share and Self-Destruct
Send the encrypted link to your recipient through any channel — email, Slack, text, or any messaging app. When they click the link, the secret is decrypted, displayed to them, and immediately and permanently deleted from our servers. The self-destructing link becomes invalid and can never be used again by anyone.
What Happens Behind the Scenes
OneTimeSecret uses a zero-knowledge architecture to protect your secrets at every stage of the process.
AES-256 Encryption
Your secret is encrypted using AES-256, the same encryption standard trusted by governments, militaries, and financial institutions. This level of encryption would take billions of years to brute-force with current technology, ensuring your data remains completely secure.
Zero-Knowledge Design
OneTimeSecret is built on a zero-knowledge architecture. This means our servers store your encrypted data but never have access to the decryption keys. Even our own team cannot read your secrets. If our servers were ever compromised, your encrypted messages would remain completely unreadable.
Automatic Expiration
Every secret has an expiration timer. If the recipient does not view the link within the set timeframe, the encrypted data is automatically and permanently purged. There are no backups, no archives, and no way to recover an expired secret.
Permanent Deletion
When a secret is viewed or expires, it is permanently erased from our infrastructure. Unlike email servers that keep deleted messages in backup systems, OneTimeSecret performs true, irreversible data destruction. No traces remain.
Security Guarantees
Every layer of OneTimeSecret is designed with security as the default, not an afterthought.
The same standard used to protect classified government communications worldwide.
All data in transit is protected by the latest transport layer security protocol.
Strict one-time viewing with permanent deletion. No re-access, no recovery, no traces.
OneTimeSecret vs Email vs Chat Apps
Why self-destructing encrypted links are safer than the channels most people use to share sensitive information.
| Concern | OneTimeSecret | Chat Apps | |
|---|---|---|---|
| Message persists after reading | No — deleted instantly | Yes — stored forever | Yes — in chat history |
| End-to-end encrypted | Yes — AES-256 | Rarely | Varies by app |
| Stored in server backups | No | Yes — indefinitely | Yes — cloud sync |
| Searchable by others | No | Yes — inbox search | Yes — chat search |
| Sender knows if viewed | Yes — link expires | No guarantee | Read receipts only |
The Problem with Email and Chat
When you send a password through email, it lives in your sent folder, the recipient's inbox, and potentially on multiple server backups — indefinitely. Chat applications like Slack, Teams, and WhatsApp store messages in searchable histories and cloud syncs, making them accessible to anyone with account access.
OneTimeSecret eliminates this problem entirely. Your encrypted message exists for exactly one viewing, then it is gone forever. No server backups, no search indexing, no persistent storage. This is why tools like Password Pusher, Privnote, scrt.link, Yopass, and Bitwarden Send exist — to provide a secure alternative to plaintext sharing. OneTimeSecret combines the best of these tools with a strict one-time policy and zero-knowledge encryption.
