 # Warnings
 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. If you need to manage a login but don't need any password, you can keep this field empty to avoid this warning. Note: Email can also be used as a login if the member is linked to a user.
