Updating account password through API ?

I've been looking at the db structure. According to the Accounts table, there are 2 columns related to the password : "password" and "password-hash"

Question : Is the password purely managed by SQL ? if so, how can it be updated ?

Otherwise, does the SWIS API can manage account passwords ?

I've been looking for a way for users to update their password on Orion, but no luck.

Best regards,

Luc
