Password security is often a hot topic among security professionals. If you use the same password everywhere, and one site gets hacked, then you are vulnerable everywhere. Whenever a big website is compromised, hackers will often try stolen login credentials on sites like PayPal, Gmail, Amazon, etc. By having a unique password, you only have one compromised login vs hundreds of potential passwords floating around the internet. There is another way to increase security that all security professionals recommend. It's called Multi-factor Authentication and it's recommended for every website you use that supports it. In a sense, it combines something you know (your password) and something you have (an app that generates a two-factor authentication code).
