When you have 200 registered accounts over the internet, this is necessary. Perhaps it's time for a cloud pw manager? Or perhaps it could be a vulnerability itself.
I can understand using the same password for "junk services" that you don't really care about, but if you use the same password for
everything, you are just asking to be hacked.
Using unique passwords for services that are important to your security is a must. I recommend either getting a password management program or just writing them all down. I have a lot of unique passwords written physically in case I forget any of them. Most of them that I use frequently I have memorized. I couldn't remember them easily when I first created them, but that's something you learn with time.
And when it comes to creating those unique passwords:
- Don't use real words
- Use a combination of capital and lower case letters
- Use numbers
- Throw in a symbol or two
Do that and you are 10x more secure than most people on the internet.
Personal experience: I used to be a WoW player. One day about a year and a half ago, I found my account compromised by Chinese hackers who had somehow acquired my account information. I was using the same information for everything I had at the time. Through that, hackers managed to access my WoW account, my Xbox Live gamertag, my email, my Steam account, my Photobucket account, my PayPal account, and my Facebook. My Photobucket, PayPal, and email were 100% compromised and lost to me forever. Everything else I managed to get back with some effort. And that is the day that I learned the hard way to use more than one email and unique passwords for everything. You hear the same story happen to other people, and you make their mistakes anyways because you assume that it will never happen to you. But it does happen, and it's better to be safe than sorry.
