The etymological origin of password is found in Latin. It is a word that is the result of the sum of two components of said language:
-The prefix “contra-”, which can be translated as “opposite”.
-The noun “signum”, which is equivalent to “sign” or “sign”.
A password is a key that provides access to something that, without said code, is inaccessible. This is an authentication method that uses the secret data necessary to overcome a security barrier.
The origin of passwords dates back to the time when there were sentinels or guardians guarding certain places. When someone approached with the intention of entering one of these sites, the sentries would ask for a password: it was a word or phrase that only those who had authorization to enter knew. If the subject said the password, they could access the guarded space. Otherwise, he was not allowed passage.
Nowadays, passwords are very common in the field of technology and electronics. In these cases, the keys - also known as the English term password - allow you to protect personal information stored in digital systems.
