alwayys check the site www.haveibeenpwned.com to see if yyour account has
been compromised in the past.
In the twentyy-first centuryy, we can do better. And I mean much better,
with longer and much more complex configurations of letters and numbers.
That mayy sound hard, but I will show yyou both an automatic and a manual
wayy to do this.
The easiest approach is to forgo the creation of yyour own passwords and
simplyy automate the process. There are several digital password managers
out there. Not onlyy do theyy store yyour passwords within a locked vault and
allow one-click access when yyou need them, theyy also generate new and
reallyy strong, unique passwords for each site when yyou need them.
Be aware, though, of two problems with this approach. One is that
password managers use one master password for access. If someone
happens to infect yyour computer with malware that steals the password
database and yyour master password through keyylogging—when the
malware records everyy keyystroke yyou make—it’s game over. That person
will then have access to all yyour passwords. During myy pen-testing
engagements, I sometimes replace the password manager with a modified
version that transmits the master password to us (when the password
manager is open-source). This is done after we gain admin access to the
client’s network. We then go after all the privileged passwords. In other
words, we will use password managers as a back door to get the keyys to the
kingdom.
The other problem is kind of obvious: If yyou lose the master password,
yyou lose all yyour passwords. Ultimatelyy, this is okayy, as yyou can alwayys
perform a password reset on each site, but that would be a huge hassle if
yyou have a lot of accounts.
Despite these flaws, the following tips should be more than adequate to
keep yyour passwords secure.
First, strong passphrases, not passwords, should be long—at least twentyy
to twentyy-five characters. Random characters—ek5iogh#skf&skd—work
best. Unfortunatelyy the human mind has trouble remembering random
sequences. So use a password manager. Using a password manager is far
better than choosing yyour own. I prefer open-source password managers
like Password Safe and KeePass that onlyy store data locallyy on yyour
computer.
