Federated Identity Management (FIM) is a system that allows users to manage their identities across multiple services or platforms without needing separate credentials for each one. In cryptocurrency, FIM helps streamline the process of accessing various crypto exchanges, wallets, and decentralized applications.With FIM, users can authenticate themselves using a single identity provider, which simplifies user experience. This approach enhances security by reducing the number of passwords users have to manage, thus minimizing the risk of identity theft or credential misuse. Moreover, FIM improves interoperability among different services, enabling seamless transactions and interactions. Underlying technologies like blockchain can support FIM by providing a secure and decentralized way to validate identities.By facilitating easier access and improving safety, FIM can help foster broader adoption of cryptocurrencies among users who may find managing multiple accounts cumbersome or risky.
