Here are a few ideas for creating strong passwords and keeping them safe:
Use at least 10 characters; 12 is ideal for most home users.
Try to be unpredictable – don’t use names, dates, or common words. Mix numbers, symbols, and capital letters into the middle of your password, not at the beginning or end.
Don’t use the same password for many accounts. If it’s stolen from you – or from one of the companies where you do business – thieves can use it to take over all your accounts.
Don’t share passwords on the phone, in texts or by email. Legitimate companies will not ask you for your password.
If you write down a password, keep it locked up, out of plain sight.
Consider a password manager.
Most people have trouble keeping track of all their passwords. Consider storing your passwords and security questions in a password manager, an easy-to-access application that allows you store all your valuable password information in one place.
