smbpasswd

Add/remove a Samba user or change its password. Samba users must have an existing local Unix account. More information: https://manned.org/smbpasswd.8.

• Change the current user's SMB password:
  smbpasswd
• Add a specified user to Samba and set password (user should already exist in system):
  sudo smbpasswd -a {{username}}
• Modify an existing Samba user's password:
  sudo smbpasswd {{username}}
• Delete a Samba user (use pdbedit instead if the Unix account has been deleted):
  sudo smbpasswd -x {{username}}
