Unfortunately another drawback is that SSO (in general) makes XSRF even
more dangerous as logging in one malicious site or if you have a Trojan
might compromise your data in several others sites and open the door to
a chain reaction similar to the XSS worm for Myspaces.
However SSO is a need for many people that anyway use password recycling
to obtain the "same effect".
If well used SSO could be beneficial as you can learn one single strong
password than dozens of easy-to-remember.
Notice the "if well used" at the beginning of the statement "there is no
patch for stupidity"

Yes, it is difficult to configure it for supporting sites.
But it does save us from registering at multiple webistes &
remembering the passwords of each of them.
It also makes it that much simpler for a malicious user to gain access
to every account you have after getting the password for only one.
If you use a different account name and password at every single
website, then if one account is compromised then all your other accounts
are safe.
