 WarningPasswordSetWithNoAccount=A password was set for this member. However, no user account was created. So this password is stored but can't be used to login to Dolibarr. It may be used by an external module/interface but if you don't need to define any login nor password for a member, you can disable option "Manage a login for each member" from Member module setup.
