Sharing passwords is a security risk.
Do not divulge your password to any one.
Enter your user-id and password only in the space
provided for- that you are normally used to.
Do not provide user-id and passwords on any page that
appears as a popup when you click on a hyperlink received
through email. Better practice would be to log on to the
service by typing in the URL in the address bar after making
sure the page opening up is from the genuine service
provider.
Do not store passwords in a file on ANY computer system
(including Palm Pilots or similar devices) without
encryption.
Change passwords at least once every 90 (ninety) days.
Unique Characters An acceptable password must have at
least five (8) different characters. Repeated characters can
make for palindromes and make it easier to crack.
Character Types- An acceptable password must have
characters from at least three (3) different character types
-- upper case, lower case, digits, punctuation, etc. A
password that includes a sample from a rich character set is
difficult to crack.
Forbidden Characters There are a few characters that
will cause problems if used in a password - the "delete"
character is one of the obvious ones.
Writing down your password One should never write down
a password. Someone may discover the password. Make the
password difficult for others to guess or crack but easy for
you to memorise and remember.
One possible method for picking a good password is to
make up your own acronym.
Do not let your computer remember your password . Do
not accept auto complete option provided by your computer/
browser.
