How to Use Passwords Securely

Every day, more and more services and applications require password authentication. For this reason, we will be looking at the risks of using the same password for various services, and we’ll go over some tips for making them more secure.

Passwords have become, without doubt, the Internet’s ID card. Thanks to passwords, a user can prove who they are and unauthorized access can be prevented. However, by the same token, should a malicious user steal or discover this data, they can assume a user’s identity and access services and applications.

One of the basic rules for choosing a password is to ensure it is both long and complex in terms of characters. As a rule of thumb, a good password is a least eight characters long and comprises a mix of letters, numbers and special symbols (eg. “ke8_SP.2”).

Although creating a good password is not difficult, with so many services requiring password authentication, remembering them can be a problem, especially as the objective is to avoid having a series of numbers and letters that are easy to guess or remember.

To prevent having to remember a variety of different complex passwords, many users have same password for different applications, services etc. Unfortunately, this increases the risk of an attacker stealing users’ digital identities, as the password could be stored in applications and potentially accessible to others. If the same password is used for using a computer, accessing web mail and electronic banking, an attacker who cracked one of the passwords would have simple access to the others.

To summarize, it is important to use different passwords, especially when it comes to services with confidential information (such as online banking services), and only use simple passwords for less important services (for example subscription to online newspapers, etc.).
