In a connected world, login is present in the routine. We use this method of access in emails, social networks, games and others. However, few people know more than the basics – for example, the meaning of the term “login”. In the following, we will explain details about this mechanism that is so essential for security on the web.
What is login?
The concept of login is in the name itself, originated from the English term logging in, which means to connect. It is a set of credentials that identify users on a website, social network, email etc. Through this mechanism, users can not only access their accounts more securely, but also make changes to them.
One of the main objectives is to prevent important data, such as e-mail and security passwords, from being stolen. Although hacking methods are increasingly complex, login remains important. The most well-known standard is one that requires an email and password, but there are others that require biometric identification with fingerprint, voice and even facial recognition.
Because it is necessary?
In a world without a login, anyone could have easy access to personal and sensitive information; it is possible to compare it to a bank password. Imagine a scenario in which there is no form of identification in banking institutions (we need not say that chaos would ensue).
In the face of new threats to user security, more secure login methods have emerged that include, for example, two-step authentication (also called 2FA), present on WhatsApp, Instagram and Google accounts. Another example is the requested account verification when the system identifies an unusual login.
Depending on the service, the software or the platform, the login may consist of more than one form of authentication, as mentioned. Currently, this is one of the safest methods, used mainly to prevent the theft of information and account credentials. Check out some examples.
Once two-step authentication is activated on the Google account, the system links the login to a user’s Android device. Thus, whenever access is made on a new device, a notification will be sent to the cell phone, allowing to allow or not to login.
