The private life is often protected by some kind of key. From the earlier phases of the human life, we can see that a key for our home always existed. With the time, people discovered a word called password because they had to protect their privacy in different areas in their daily life. The technology became not only a friend, but also an enemy.
The latest phase of the human life is the Internet, as we all know. In that network, many people live in fear. They want to have the access to the Internet, but they are careful and do not want to be locked out. They need to remember the passwords. Unfortunately the life on the Earth has turned in to a cruel life. The technology has made people dependent of it. How do we protect ourselves?
Using passwords is a method that still works. It is a good method but it is stressful. What if we have several passwords? If a person forgets a password, it can be a very difficult process of getting a new one. It is so especially in big companies with free services and those who do not offer a human contact. That is why people are in horrible position. It can be very confusing with different passwords for different logins.
However, in some systems it is not necessary to have a password and automatically you can not forget it. It is enough to have an e-mail address and one good password only. When you need to log in, the system sends you a code and you write it on a log in page. The code works in 60 seconds and afterwards you have to ask for a new one, if needed. So simple is it. But is it a safe method? It should be safe as long as you have a good password for your own e-mail address and the servers who manages this procedure are not hacked.
