How can I change my password?

Simply login to your account and visit the “Account Details” page. We recommend you choose a strong password for your account so as to increase the security.

Common guidelines for choosing good passwords are designed to make passwords less easily discovered by intelligent guessing:

• Include numbers, symbols, upper and lowercase letters in passwords
• Password length should be around 5 to 14 characters
• Avoid any password based on repetition, dictionary words, letter or number sequences, usernames, relative or pet names, or biographical information (e.g., dates, id numbers, ancestor’s names or dates …).
• If the system is case sensitive use capital and lower-case letters
• Password should be easy to remember for the user

Examples of weak passwords

As with any security measure, passwords vary in effectiveness (i.e., strength); some are weaker than others. For example, the difference in weakness between a dictionary word and a word with obfuscation (i.e., letters in the password are substituted by, say, numbers — a common approach) may cost a password cracking device a few more seconds. The examples below illustrate various ways weak passwords might be constructed, all of which are based on simple patterns which result in extremely low entropy:

• Default passwords (as supplied by the system vendor and meant to be changed at installation time): password, default, admin, guest, etc.
• Dictionary words: chameleon, redsox, sandbags, bunnyhop! Intensecrabtree etc
• Words with number substitutions: password1, deer2000, john1234, etc
• Words with simple obfuscation: p@ssw0rd, l33th4x0r, g0ldf1sh, etc
• Doubled words: crabcrab, stopstop, treetree, etc
• Common sequences: qwerty, 12345678, mnbvcxz, etc
• Numeric sequences based on well known numbers such as 911, 314159, or 27182, etc
• Identifiers: jsmith123, 1/1/1970, 555-1234, “your username”, etc
• Anything personally related to you: license plate number, social security number, current or past telephone number, student id, address, birthday, relatives’ or pets’ names/nicknames/birthdays/initials, etc.

There are many other ways a password can be weak, corresponding to the strengths of various attack schemes; the core principle is that a password should have high entropy (usually taken to be equivalent to randomness) and not be readily derivable by any “clever” pattern, nor should passwords be mixed with information identifying the user.
