Introduction
A modern utility library for authentication and cryptographic workflows
Keylio is a modern, type-safe utility library that simplifies authentication and cryptographic operations in Node.js and TypeScript applications.
It provides a unified, developer-friendly API for common security tasks, allowing you to focus on building features instead of wiring low-level libraries together.
Keylio is designed to be simple, opinionated, and production-ready - without locking you into complex abstractions.
Adapter Support
Currently, Keylio exclusively supports Prisma adapters. Support for other database adapters is still in development.
What Keylio Solves
In many projects, authentication logic quickly becomes fragmented across multiple libraries and configurations. Keylio brings these concerns together under a single, consistent interface, reducing boilerplate and potential security pitfalls.
Instead of managing raw dependencies and repetitive setup, you get sensible defaults and a clean API out of the box.
Core Features
Keylio provides utilities for the most common security-related workflows:
Password Hashing
Secure password hashing and verification built on top of bcrypt.
Token Management
Generate and validate JSON Web Tokens (JWT) using jsonwebtoken.
Identity Utilities
Create unique, collision-resistant identifiers powered by uuid.
Type Safety
Fully written in TypeScript with strong typing across all public APIs.
Who Is Keylio For?
Keylio is ideal for:
- Backend developers building Node.js or TypeScript APIs
- Projects that need simple but secure authentication utilities
- Teams that value clarity, type safety, and maintainability
- Developers who want fewer dependencies and less configuration noise
You don’t need to adopt everything at once - Keylio utilities can be used independently.
