Change Password

A password is the most basic mechanism of security, and is often the only control protecting your private information. These simple tips will help you maintain your passwords:

  • Choose a strong password that you will remember.
  • Choose a unique password for each of your accounts.

  • Separate your work and personal accounts and make sure that your sensitive accounts have the strongest passwords. 

  • Never share your password!

  • Change your password if you suspect it has been compromised.

  • If you write it down, keep it safe in a secure place away from your computer. Consider a password manager service to keep track of passwords. Ask your IT support person for more information.
