Choosing a smart password

Phishing, a topic that's been in the news, is unfortunately a common way for hackers to trick you into sharing personal information like your account password. If you suspect you've been a victim of a phishing attack, we recommend you immediately change your password, update the security question and secondary address on your account, and make sure you're using a modern browser with anti-phishing protection turned on.

It's a good idea to use unique passwords for your accounts, expecially important accounts like email and online banking. When you create a password for a site, you might think of a phrase you associate with the site and use an abbreviation or variation of that phrase as your password — just don't use the actual words of the site. If it's a long phrase, you can take the first letter of each word. To make this word or phrase more secure, try making some letters uppercase, and swap out some letters with numbers or symbols. As an example, the phrase for your banking website could be "How much money do I have?" and the password could be "#m$d1H4ve?" (Note: since we're using them here, please don't adopt any of the example passwords in this post for yourself.)
