Show HN: SimpleAuth.link – Selfhosted passwordless service with no database

a year ago

SimpleAuth.link is a secure authentication service that enables your users to log in to your platform without the need for traditional passwords. Using the service, other apps or platforms can verify user identities and manage active sessions through cryptographically generated tokens.

Token Generation Process

- By leveraging the Ed25519 signature algorithm, the service deterministically generates a private key using your App ID and secret.

- This ensures that each token is cryptographically secure and uniquely tied to your application, eliminating the need to store sensitive keys.

Stateless Architecture

- SimpleAuth.link works without a traditional database. It does not store any user data, including email addresses, on its servers.

- Instead, the data generated is self-contained, requiring no further information or state to be used. This stateless design increases security and reduces the risk of data breaches.
