Maybe it is feasable to offer users different levels of
security for loggin in.
If it is going to be a one-off hi-value financial
transaction, then allow the user a higher level of security
for logging into a site, to complete that transaction.
Otherwise, just use the standard logging in methods of
username and password.
Alternatively, why not use two passwords, and a username.
My online bank uses a system of picking random numbers from
my password, and asking me to match those numbers with a
drop down box, instead of just typing in the exact password
in the same format at each login.

Hi Michael,
Interesting idea. Not unlike the way credit card companies will
sometimes phone you before authorizing a large transaction (never
happened to me, but they claim they do it). I think this is good as
supplemental authentication, but the delay waiting for the email and
such probably make it unsuitible as the main authentication technique.
In addition, if it is the ONLY authentication technique, then compromise
of the email account means compromise of all accounts using this
authentication.
Perhaps an interesting variation would be to SMS a pass code to a mobile
phone.
In fact, PayPal do something which is kind of similar. When you join,
they bill your card the membership fee, and put a random code in the
originator's reference. When you receive your bill and supply this
reference back to PayPal, your account is upgraded to "verified" status.
Very sensible precaution.
Regards,
Paul

Just a quick little article about a login system that, should (i

Have a look at it and let me know what you think ... and apologies
to anyone if an idea like this is already out there :)
