• Continuous authentication evaluates trust throughout a session, not just at login.
• Decentralized identity approaches give users more control over their personal data.
• AI-powered security detects increasingly sophisticated attack patterns.
• Zero Trust architecture eliminates implicit trust based on network location.

Organizations that understand these trends can anticipate changes rather than reacting to them after the fact.
