Securely Send Passwords, API Keys
and Secrets Online
Create a secure receive link and share it with anyone who needs to send you credentials. They paste the secret, it gets encrypted in their browser with AES 256, and only you can read it. No more passwords over Slack, email, or plain text.

Frequently Asked Questions
Everything you need to know about secure credential sharing.
Is it safe to share passwords over Slack or email?
No. Slack and email store messages in plaintext on their servers. Anyone with access to the workspace or inbox can read them. SecureBin encrypts everything in your browser with AES 256 before it leaves your device.
How does SecureBin Receive Mode work?
You create a secure receive link and share it with anyone. They paste the secret, it gets encrypted in their browser, and only you can decrypt it with your private key. The secret is deleted after you read it.
What encryption does SecureBin use?
SecureBin uses AES 256 GCM encryption with Web Crypto API. The encryption key is generated in your browser and never sent to our servers. We use a zero knowledge architecture.
Can SecureBin staff read my secrets?
No. We use zero knowledge encryption. Your data is encrypted before it leaves your browser. We only store encrypted blobs. Without your key, the data is unreadable.
What happens after I read the secret?
The encrypted data is permanently deleted from our servers. It cannot be recovered. This one time read design ensures your credentials are never stored longer than necessary.
Is SecureBin free?
Yes, the core features including Receive Mode, burn after reading, and AES 256 encryption are completely free. No signup required.
What is split key sharing?
Split key sharing means the encryption key is separated from the link. You can send the link via email and the key via SMS, so no single channel has enough to access the secret.
