You can check if you were included in this dump through a couple online sites. Have I been pwned.

Always a good idea to switch up passwords on a reg basis. If you use one password across a number of sites you may want to discontinue that, create unique passwords for each.

some of my old address were but current is stable.

Do you use a password manager? Know any good free ones?

You can find a list of the top ten free password managers online.

I dont use a password manager. But there are plenty out there, they are also subject to hacking. Wrtie all your paswords onto a peice of paper just keep them safe. 

Not really a tech type.
