Frequently Asked Questions
What is one-time secret sharing?
One-time secret sharing allows you to securely share sensitive text information like passwords, API keys, or confidential messages that will be automatically deleted after the first viewing. This ensures your sensitive information doesn't remain accessible indefinitely.
How do I use the one-time secret feature?
Using the Arcano one-time secret feature is simple: 1) Type or paste your sensitive information in the text field, 2) Click 'Create Secure Link', 3) Share the generated link with your recipient, and 4) The content will be automatically deleted after they view it once.
How can I share passwords safely?
To share passwords safely: 1) Use the Arcano one-time secret sharing feature instead of email or messaging apps, 2) The generated link will work only once and then self-destruct, 3) The password is encrypted end-to-end and never visible to us.
How secure is the secret sharing feature?
The Arcano secret sharing feature uses the same end-to-end encryption as our file transfers. Your secret is encrypted in your browser before being sent to our servers, and we never have access to the unencrypted content. The encryption key is part of the link you share, not stored on our servers.
How can I trust your service?
We are transparent about our security practices and do not collect or store any personal information. Our service has been audited by Cure53, the same firm that has audited Telegram and other major services. Also, our encryption code is not obfuscated and visible through your browser
How long are shared secrets stored?
Shared secrets are automatically deleted after the first access. If a secret is not accessed, it will expire and be deleted after 7 days. Once deleted, the content cannot be recovered.
Can I share files through the secret sharing feature?
Anonymous users can only share text secrets. To share files securely with the same level of encryption and security, you'll need to create a free Arcano account.
How can I send large files securely instead of via email?
Email is not designed for large file transfers and often has size limits (typically 10-25MB). For securely sending large files, create a free Arcano account which allows you to: 1) Upload files of any size with end-to-end encryption, 2) Set expiration dates and access limits, 3) Receive notifications when files are downloaded, and 4) Maintain the same level of security as our one-time secret feature.
How is secret sharing different from email?
Unlike email, which is typically not encrypted end-to-end and leaves permanent copies on multiple servers, the Arcano secret sharing feature uses end-to-end encryption and automatically deletes the content after it's viewed. This makes it much more secure for sharing sensitive information.
