I have a web designer building my web-site. I don’t want to give him my yahoo password. However, yahoo requires a yahoo account to build the site.
I’m sure not all Yahoo site owners do their own webpages.
you should give it your password then after the work finished change it
and don’t worry most designer/developer are trusted and will not still any
personnel info from you
