Admin Authentication
Hermes SEG utilizes Authelia Authentication Server for controlling access to the the Hermes SEG Administration Console. The Authentication Settings page allows you to change many Authelia settings to suit your needs.
JWT Secret
The JWT Secret is used to craft JWT tokens by the identity verification process. Hermes SEG randomly generates a 32-character alphanumeric string at the time of installation. It's usually not necessary to change this field. However, if you wish to change it, click the 
button and the system will generate a new one (Figure 1).
Figure 1
If you wish to generate your own, Hermes SEG will accept a minimum 32-character and a maximum 64-character alphanumeric string only.
Storage Encryption Key
The Storage Encryption Key is used to encrypt data in the database. Hermes SEG randomly generated a 32-character alphanumeric string at the time of installation. It's usually not necessary to change this field unless the key gets compromised. if you wish to change it, click the button and the system will generate a new one (Figure 2).
Figure 2
If you wish to generate your own, Hermes SEG will accept a minimum 32-character and a maximum 64-character alphanumeric string only.
Please note that if you generate a new Storage Encryption Key, it will break authentication for System 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).
