Electronic identity theft is a really serious problem.It affects the whole community: that means direct or indirect damage for citizens, businesses and institutions.The only way out is to use access mechanisms that allow a user to manage in a simple and secure way their credentials and to protect their own electronic identity.

Why is it strongly recommended, for your safety, to set complex and strong Passwords (even if they are hard to remember) rather than Passwords that are easy to recall?

Because the Top 5 most common passwords used in 2013 and 2014 were:

1) 123456      2) password          
3) 12345678 4) qwerty   5) abc123

....and digital criminals engaged in identity thefts know this all too well. They are familiar with  hundreds of the most typical algorithm and combinations that people use to set their Passwords

So if you have ever used a Password similar to the ones above, your data is insecure!

Why are you recommended to change your Passwords frequently?

Because every day there are hundreds people around the world trying to identify other people's passwords, using effective software that can repeat thousands attempts until they finally crack your password.

Is it better to fix an easy-to-remember Password in your mind or to write down a strong one somewhere?

Easy passwords - like the ones based on your or your relatives' birth-dates, the name of your dog, etc - are absolutely unsafe and can easily to be discovered. If you have a problem remembering a complex strong Password, it's much better to write it on a piece of paper and hide it in a very safe place that only you know.
