A
How safe in personal information on your computer or cellphone? Not very safe, potentially. Despite this, there are some simple steps you can take to make your online experience safer.
Manage passwords
What we pick as passwords and how we manage them are important, according to Murat Kantarcioglu, professor and director at the Data Security and Privacy Lab at the University of Texas at Dallas. First, passwords should never include your personal information. Ideally, passwords are a combination of lowercase（小写）and uppercase（大写）letters and random characters.
It could be harder to remember, but that's why password managers are good to use for some websites. Kantarcioglu does not recommend using password manager apps for sites that have sensitive information, however. Store them in your brain.
View emails with a careful eye
Deceptive phishing（欺诈性的网络钓鱼）is one of the most common types of trick. Hackers（黑客）can make emails look like real company emails that can trick readers into clicking on dangerous links. You could end up introducing a virus to your computer or giving sensitive information to the wrong people. It's best to search for the original source of the information and find the direct link from the site instead of using the link provided in the email.
Use two factor authentication
Two-factor authentication（双重认证）adds a second level of security to an account. It's a security option that requires a password as well as an additional piece of information only the user would know. Sometimes, it's a code sent to your cellphone that has to be entered after a password. The additional feature can keep your information much safer.
