Future-proofing IAM involves moving beyond traditional password-based authentication and incorporating methods like biometrics and multi-factor authentication. Additionally, identity-proofing, which links claimed identity with actual identity through document verification and biometric verification, enhances security and prevents credential theft. Implementing zero-trust principles and the principle of least privilege can further strengthen IAM and mitigate security risks. By embracing these advancements, organizations can protect their digital identities and streamline their digital lives.
