Simple Login

Simple Login

General Overview

Simple Login is a UK-based company specializing in hosted authentication infrastructure, aimed at developers, app creators, startups, freelancers, and indie hackers. It offers a secure, ready-to-use solution that allows for quick integration of authentication flows without the usual technical complexities (source: homepage of simple‑login.com) (simple-login.com).

History and Origins

Simple Login was born from the observation that developers spend too much time rebuilding authentication systems for each project. The team, composed of engineers who have already implemented authentication systems in startups and side projects, decided to create a reusable infrastructure to focus on what matters: the product (source: About page) (simple-login.com).
