I've said it before and I'm going to say it again; when you use the same password on multiple accounts, you're making it too easy for the bad guys to compromise you. The primary suggestion for avoiding this mistake is to use a management tool, of which there are many free options such as https://www.lastpass.com or https://www.roboform.com Now, some people find these programs to be too confusing or complicated, so my next suggestion is to simply write them down yourself. You can create a generic file that doesn't have any reference to the word 'password' that contains all of your usernames and passwords. As an extra layer of protection, create your own secret code, like 4 characters that mean nothing in front of the actual password, so if anyone finds the file, they still won't figure out what your password without breaking your secret code. With the number of companies that you work with every day getting compromised on a regular basis, if you have to decide whether to use the same password everywhere or write down long, complex but unique passwords for each account, its pretty obvious which is safe
