No more logging in to public computers

Today one of the Chief Security Officers from my university came to speak in an educational technology workshop that I have been involved in all week. He cautioned everyone NOT to log into public computers because that computer could then hold your private credentials, which could potentially be stolen. So, this means...Internet cafes, presentation work stations, etc. It is best practice to use your own computer, laptop, or phone to check your email, and not log on to someone else's machine or a public work station. How many times have you logged into your email on someone else's computer or at an Internet cafe? I won't be doing that anymore.
