VT Password Info

VT will expire your PID and Hokies passwords once a year.

• How to change all your VT passwords: http://computing.vt.edu/kb/entry/3924
• Creating strong passwords: http://www.awareness.security.vt.edu/passwords/strong_passwords.html

Use a passphrase instead of a password

At the most basic level, a password's strength is derived from it's length. The longer the password, the better. Passphrases tend to be easier to remember and type, while still remaining very strong and hard to crack.

For example, a passphrase of 4 words and 28 characters, "correct horse battery staple", is stronger than a password of 11 characters and high complexity, "Tr0ub4dor&3"

This XKCD comic illustrates the issue: https://xkcd.com/936/

Suggestions for creating a passphrase

• Choose some words from your favorite poem, book or movie, preferably at random.
• Use a nonsensical phrase of words, something that has meaning to you.
• Choose words at random, or using a system like Diceware
• DO NOT use common phrases, such as "An apple a day..."
• Try to limit any personal information (names, dates, addresses) in the passphrase

Type it out. Make sure it is at least 4 words long. Now, because almost all sites require AlphaNumeric + Special characters, you should capitalize one or more words and add punctuation. Be sure to include spaces.

• Example: Correct horse Battery staple!

Use a password manager

Password managers are programs that will protect and save your account info and passwords to your computer. These programs use a master passphrase to encrypt all of your passwords, making it easy to update and find all of your passwords.

We strongly encourage you to use a password manager to create a unique password for each web account you have.

• We recommend using Keepass as your password manager.

Using KeePass

Windows

1. Download Keepass Professional Edition (Version 2.X)
2. Install Keepass with the default options
3. Open Keepass
4. Create a new KeePass database, open the File menu and select New
5. Name the database and save it to your computer
   • We recommend saving the database file to your VT Google Drive folder or Documents folder
6. Enter a Master Password, twice.
   • Again, we recommend using a "Master Passphrase" of 4 or more words with capitols, spaces and punctuation.
7. Accept the default Database Settings and select OK
8. Now you can start creating new entries. On the left are the entry groups or folders, and on the right are the password entries.
   • There are a few example groups and entries, you can safely modify or delete them as you like.
9. To add a new password to the KeePass database, open the Edit menu and select Add Entry...
10. Fill in the necessary fields (Title, Username), and add any notes or URL's if you desire
11. We recommend using the KeePass password generator to create new passwords, or you can type in your own password
    • The Generate a password icon is to the right of the second password field

OS X or Linux
