It's not a secret that passwords are a relic from a different century. However, modern cryptography provides us with far better means to authenticate with applications, such as Ethereum's Secp256k1 public-private key pairs. This article is a complete step-by-step deep-dive to securely establish a Ruby-on-Rails user session with an Ethereum account instead of a password. In addition, it aims to explain how it's done by providing code samples and expands on the security implications.
