Strong authentication refers to the multi-layered approach used to verify the identity of users in cryptocurrency transactions. It typically involves using two or more methods to confirm a user’s identity, making it more difficult for unauthorized parties to gain access to accounts or perform transactions.Common methods of strong authentication include something the user knows (like a password or PIN), something the user has (like a smartphone app or hardware wallet), and something the user is (biometric data like fingerprints or facial recognition). By combining these factors, the security of transactions is significantly enhanced.This approach helps protect against common threats such as identity theft, phishing attacks, and unauthorized access. As the market evolves, ensuring robust security measures through strong authentication becomes increasingly crucial for both users and service providers, fostering trust and confidence in the system.
