Security has to be a prime concern when doing anything online. The number one action you can take to be more secure is to use a different password for every web-site or service you sign up for. The trouble is, you will have probably a good 20 or 30 right now and with matched betting you will join at least another sixty sites.
Now, you would think that trying to manage that number of passwords and keep them all unique would be hard, but actually it’s easy. If you use a password manager you will have to remember no more than two passwords, one for your computer and one for the password manager. The password manager will keep all your passwords nice and secure by using encryption so no-one, anywhere, can access them. Baddies can try to access the passwords but it will take them longer than there are atoms in the universe.
You don’t even need to see the passwords because a good password manager will allow you to generate a new password at the time you are signing up for a service (which means all that you see is a line of *), and then remember the site details for you. Whenever you visit the site or service after that the password manager automatically logs in for you!
There are plenty of password managers out there but the one I use (I have tried a few of them over the years) is called Sticky Password and is by far the best one I have ever used. It costs a small amount but will save you that in time and hassle, I recommend you give it a try.
