Enter the passcode in the One-time passcode box and the encrypted email will open. If you are on your computer (not a public computer) and expect to receive additional encrypted emails in the next 12 hours, select This is a private computer. Keep me signed in for 12 hours.

• One-time passcodes are good for only 15 minutes after they are requested.
• Select This is a private computer. Keep me signed in for 12 hours only if you are on a private computer.
• Information security is EVERYONE’S responsibility.
