There is growing interest in alternatives to conventional techniques like username and password combinations due to the growing requirement for safe and effective authentication and authorization systems. Token-based solutions, like the OAuth framework, are one such possibility. But there are a number of problems with how OAuth is currently implemented, including poor performance, a lack of privacy, and vulnerability to security risks. These problems are addressed by the revolutionary token-based authorization method called Fire OAuth that we provide in this work. Our technology offers quicker, safer, and more private authentication and authorization by combining cryptographic methods with a decentralised design.
