double key encryption

Double Key Encryption (DKE) is a Microsoft 365 security feature that requires two separate keys to decrypt protected data, ensuring that even if one key is compromised, the data remains secure. On WindowsForum.com, discussions highlight DKE's expansion to Android devices, previously limited to Windows, Mac, and iOS, marking a significant step for cross-platform data protection. The feature is critical for maintaining data integrity and compliance in heterogeneous device environments. Additionally, DKE is referenced in the context of U.S. House of Representatives' adoption of Microsoft 365 Copilot, where security measures like DKE underpin the controlled pilot for congressional staff. These threads emphasize DKE's role in enterprise security, particularly for organizations handling sensitive information.
