 Cryptomator protects your data by ingesting it in a so-called vault, which is mounted to a virtual drive and password protected. To access and view the data, you must unlock the vault with the created password. The data is stored on the cloud of your choice when creating the vault, but is encrypted automatically by the Cryptomator client. It is only from the virtual drive which act as a USB flash drive that you can access and view the data, as it shows the decrypted view of its content. Ingesting your files directly into the virtual drive permits Cryptomator to automatically encrypt the data with AES and 256-bit key length.

-## Setting up key management system with Cryptomator Hub
- Cryptomator Hub adds key and access management to your vaults from a central component deployed on your infrastructure, permitting collaborative work. As an admin, you can share your vaults with other people, who can access the vault by authenticating with Keycloak. There is thus no need for creating new accounts nor sharing encryption passwords with collaborators which are easily stolen, copied, or misused, and no data is shared on any online services. 
+## Cryptomator Hub
+ Cryptomator Hub adds key and access management to your vaults from a central component deployed on your infrastructure, permitting collaborative work. As an owner/administrator of a vault, you can share your vaults with other people, who can access the vault by authenticating with Keycloak. There is thus no need for creating new accounts nor sharing encryption passwords with collaborators which are easily stolen, copied, or misused, and no data is shared on any online services. 
 
 As a vault administrator it is important to manage the admin password properly. In case you lose or forget the admin password, a recovery key is needed to restore access to the vault. This recovery key is generated upon creating the vault (see guide below). In practical, it is the responsibility of the project manager and/or PI to manage and store the admin vault password securely. Please use passphrase and proper password management when creating the admin vault password. For further information, visit the How-to Card on [password management]( https://howto.lcsb.uni.lu/?access:passwords).
