Just a bit more about Password Managers. We're encouraged to have passwords that are not easily guessable and not re-used across different on line services. If you've only got one or two to worry about this might not be a problem but when you run in to 10s of different services it gets hard to remember which is for which. If you can remember them at all.

What a Password Manager does for you is make life a little easier. It will generate complex passwords for you and store them against the service log in details. In addition it will tell you what strength the password is, when you last changed it and if you've used it across other services.
All the details are stored in an encrypted database and the program has to be opened with a master password which should be hard to guess but also memorable.
So, having got your Password Manager installed, you'll see in your Browser toolbar line a small icon for it meaning the program has been added as an extension to your browser. If you then goto your web site of choice to login and enter your username and password you should get a prompt from the PW Manager to save the details. If you do so, then the next time you visit the same web site it will indicate that it knows this web site and it can fill in the details for you. Additionally within the PW Manager is the option to click on the service you want and it will open your browser and log you in. The caveat is that sometimes web site login pages may change and this second method doesn't always work. Its usually easy to work around this.
You can store other personal details as well, such as Credit Card numbers, addresses etc -all of which are stored encrypted.
What the paid for versions are also providing for you is the service to have all your username/password/details stored on their servers so they are accessible from across diffent devices. In other words a central database of yours in the cloud. If you like this option then OK, but I prefer not to sync my data to their servers and because of this I get to use the PW Manager for free.
Browsers like Chrome and Firefox also have the ability to store log in and password details for you but how good these are I can't say.
