Folks,
A slightly curious article but with a very good comment...

Choc Factory research shows users just don't get security

websites that demand that you must give them your login:

"Password managers don't have to be run 'in the cloud' - they can be
standalone applications running on your computer, and which should
therefore continue running long after the developers have gone." -- VinceH
Here's mine:
echo -n 'mymainpassword myusernameforthewebsite thewebsitename' |
sha256sum - | xxd -r -p | base64 | tr 'a-m' '!--' | cut -c -20 | xclip
When my browser can't remember a password, I just run that script in a
terminal, then middle key click the password input field to paste a
twenty character password, with 6 bits of entropy per character. If you
used the literal values in the case above it would be: 3"'MnsKA-&t74GD&,GxE
For stupid accounts that insist on alphanumeric only, replace the 'tr'
command (with something like sed "s/[+/=]//g"). The script works with
very little modification on windows too. I also have a version that does
a non-echoing prompt for the main password, but I tend not to bother
with that now unless I'm aware I may be overlooked (but it's also good
if you don't want it to end up in your shell history):
read -s -p "Password:" PASSWORD && echo -n "$PASSWORD
myusernameforthewebsite thewebsitename" | sha256sum - | xxd -r -p |
base64 | cut -c -20 | xclip
#####
Note the clever use of a password salt for the generated site specific
password...
There must be an easier way to all these pesky logins!
Cheers,
Martin
