detail.loadingPreview
Automate user authentication and registration effortlessly using Google Sheets as your user database and Redis for lightning-fast data caching. This workflow provides a flexible login system that can be triggered by Telegram messages or integrated into other workflows, ensuring a smooth and responsive user experience.
About This Workflow
This robust n8n workflow streamlines user management by acting as a versatile login and registration system. It intelligently checks for existing users in a Redis cache for immediate responses, falling back to a Google Sheets database for primary storage. If a user is new, it automatically registers them and updates the cache. Ideal for building custom bots, internal tools, or any application requiring a simple yet effective user authentication layer without the overhead of a traditional database, offering both performance and ease of data management.
Key Features
- Google Sheets as User Database: Easily manage user data with a familiar spreadsheet interface.
- Redis Caching for Performance: Accelerate login and user data retrieval with an in-memory cache.
- Telegram Integration: Directly handle user interactions and login requests from Telegram.
