Please note that if you generate a new Storage Encryption Key, it will break authentication for adminsSystem Users that utilize 2FA devices.

Before generating a new Storage Encryption Key, ensure you first delete any 2FA devices for each System User by navigating to System --> System Users --> Edit, click the Delete 2FA Devices button in the Edit System User page and set the Access Control Policy to One Factor. After generating a new Storage Encryption Key, you can go back and set the Access Control Policy to Two Factor and have the users re-register their 2FA authentication devices. (Figure 3).
