Regiatration FAQ

Q. How to choose a secure password?

A. Passwords should be at least 10 characters long and only include the letters A-Z, a-z, and the numbers 0-9. Passwords are case sensitive.

To ensure your password is secure you should:

Mix upper and lowercase letters and numbers in your password.
Ensure you do not use your name, your company name, CVD, e6, your date of birth, the current year or other common words as part of your password, there are easier to guess.

A good strategy is to pick a phrase that you will remember and use the first letters from that phrase, for example:

Phrase: "The best holiday I ever had was in San Sebastian"
First letters: "TbhIehwiSS"
Replace some letters with numbers: "TbhI3hw1SS"< /li>

Note: Remember most passwords are not "cracked" by anonymous "hackers", but usually discovered by reading the post-it stuck to your monitor, the note in your diary, the passwords.doc file on your hard drive or the entry in your mobile phone phonebook. So, pick a password you can remember and don't need to write down.

Q. What is the Verification Text?

A. The distorted verification text image you see on the registration form is a security test that prevents malicious computer programs from registering false accounts on our website. Current computer programs cannot read the distorted verification text but humans usually can.

If you are having problems reading the text, simply click the "Try another" button to get a new verification text.

This kind of test that tries to tell the difference between computers and humans is called a "Turing Test". This particular test called a "CAPTCHA". This is an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart".
