Session Variant

RFC-7616 specifies a mode of operation referred to as the session variant. A hash of the password, and some other fixed values, is used instead of the actual password. This allows the operation without needing to store the password in any retrievable way. This can be useful to enhance security on the client side when using local user accounts, including the built-in admin. The client can then store the hash of the admin password, rather than storing the actual password.

This can also be helpful on the SonicWall side during session security. Refer to Password and Password-Hash Saving.
