One-Time Secret is a one-time secret link service for sharing passwords, private messages, or private links. Its purpose is straightforward: to avoid leaving sensitive information such as passwords directly in emails or chat logs. Once the recipient opens the link, the secret is displayed only once and then deleted from the server; unopened content is also automatically cleaned up after its configured lifetime.
In terms of protection, it is closer to a “temporary sensitive text transfer” tool than a full password manager or DLP system. Users can set an expiration period, with options ranging from 5 minutes to 7 days. Unviewed secrets from anonymous users are retained for up to 7 days, while free accounts can keep them for up to 14 days. Privacy options include a passphrase: the server does not store the passphrase in plaintext, only a bcrypted hash, and the secret is encrypted with the passphrase, making it more secure when an additional passphrase is used. The service also offers random password generation, free accounts, an API, and open-source code that can be audited or self-hosted. Custom installations are available by contacting the team.
The main site states that registration is free. Free accounts can use secrets with a maximum lifetime of 14 days, send secret links by email, and access the API. Paid features are only described as supporting larger message sizes; no pricing, plans, payment methods, or SLA details are disclosed. For deployment, users can either use the hosted online service or self-host it based on the open-source code, making it suitable for teams with data residency or control requirements.
Its strengths are simplicity, ease of use, and open-source transparency. It can effectively reduce the risk of sensitive information being retained long-term in communication tools. The one-time viewing and automatic expiration mechanisms also fit temporary credential exchange scenarios well. Limitations include no support for images or files, and a maximum message size of 100KB for anonymous and free accounts. The main content does not mention enterprise security features such as audit logs, organization management, alerts, permission tiers, or compliance certifications, so it should not be used as a replacement for an enterprise password vault or key management system.
It is suitable for individuals, developers, operations teams, customer support staff, or small teams that need to temporarily send passwords, tokens, or private links. Larger organizations that require centralized permissions, compliance reporting, and enterprise support should consider alternatives such as Bitwarden Send, 1Password sharing, Keeper One-Time Share, or self-hosted options like PrivateBin and Yopass. The source text does not provide information about access from mainland China, so network connectivity and payment methods need to be tested in practice.
