Password Rules and Recommendations

Your Dartmouth password must conform to certain rules in order to be accepted as a valid password. If your current password does not conform to these rules, you should change it to one that does.

Rules

Password must meet the following criteria:

  • At least 8 characters (Note: if you are an alumni who still uses BlitzMail or WebBlitz your password must be exactly 8 characters)
  • Must contain at least one of the following special characters !#$%^*_
  • The last two characters can only be letters or numbers.

Examples 

  • Acceptable password construct: apple$go or a$pplego (note location of the special character $)
  • Unacceptable password construct: applego$ or appleg$o (note use of special character but in wrong position) or apple2go (note lack of special character)

The use of a special character in any place other than the last two positions creates a strong password that is difficult to crack (in excess of 30 days of computer time to crack a single password). Likewise, passwords constructed in this manner are difficult to guess (but tough to remember), especially if you select random letters and numbers. The best choice is to pick two words or abbreviations that have nothing in common and join them with one of the special characters. For example, shoe%lye (the words "shoe" and "lye" are totally unrelated, thus hard to guess, but easy for you to remember).
