I just wanted to share a tool that I use to keep track of all of my online passwords. (currently over 300 usernames and passwords)
The tool is called LastPass, which is an online password manager that works on desktop and mobile.
This handy little app when installed will save your passwords and also pre-fill them on websites when you are at the login page.
I see a lot of people use the same password or same combination of passwords for all of their logins but this is a bad idea.
Password reuse is a serious problem because of the many password leaks that occur each year, even on large websites.
When your password leaks, malicious individuals have an email address, username, and password combination they can try on other websites. If you use the same login information everywhere, a leak at one website could give people access to all your accounts. If someone gains access to your email account in this way, they could use password-reset links to access other websites, like your online banking or PayPal account.
This is why you should use a different username and password on different websites and services.
If you want to sign up to last pass they have a free option to get you started.
