Alphanumeric Passwords

Alphanumeric passwords are possibly the simplest form of protection, containing letters and numbers and creating a password. These forms of passwords may include simple forms such as the letter and number combination of, say, ‘abc123’ or the alphabetic and numeric form of something more elaborate, such as ‘A1b2C3d4’. This is because, apart from the 26 letters of the alphabet, there are also 10 numbers available, which means that the chances of an unauthorized user getting the right password are reduced. Even if the passwords are alphanumeric, they are simple to develop and memorize, and in terms of security, they are only determined by their length and the level of randomness they have.

Benefits of Alphanumeric Passwords

  • Increased Security: A combination of letters and numbers in passwords enhances the complexity standard of passwords more than those using only alphabets or numbers, thereby making it difficult for attackers to compromise the passwords by breaking the codes through hacking.
  • Compatibility: Due to their common nature and flexibility of use, alphanumeric passwords are capable of being used on most systems and platforms without conflicts.
  • Ease of Creation: They are relatively uncomplicated to formulate and memorize as compared to other password forms, such as those that embed the use of special characters as well as biometric data.
  • Balancing Security and Usability: Alphanumeric passwords are intermediate degrees of passwords since they offer a fair degree of protection against unauthorized access but are also easy to manage for day-to-day usage.

Types of Password

Passwords are a type of secret data in the form of a string of characters and are the first gateway for digital defenses, through which personal and professional information is protected against intrusion. In this article, we look at different forms of passwords used in the current society, which is faced with increased threats in the cyber world.

As a starting point, this introduction shares information about password types, making use of their distinctive features, advantages, and potential weaknesses.

While short and complicated passwords may be difficult to memorize, passphrases build on the length and entropy of multiple words and numbers and are more secure but manageable. For instance, if a password is formed from the words “CorrectHorseBattery Staple”, the password is far more complex to hack than if we assume a four-digit numerical code....

3. PIN (Personal Identification Number)

A PIN can therefore be described as a numerical code used to validate one’s identity on diverse platforms, for instance, in the banking sector, facility security, and electronics. The password is normally an alphanumerical code with four to six digits, in essence, it is designed to be easily recalled by the user while at the same time being a fairly secure form of authentication. Selecting PINs is often accomplished at the same time for multi-factor authentication that can include tokens and biometrics....

4. Biometric Passwords

Biometric passwords involve standards that involve the physiological or behavioral traits of an individual and include fingerprints, iris scans, facial features, and dactyloscopy, respectively. These are passwords that rely on body intrinsic values, which cannot be imitated or hacked. Biometric authentication improves on the traditional methods of authentication and grants the right to use a system or device only to the right person since each person’s biometric information is unique and cannot be forged or copied by another....

5. Pattern-Based Passwords

Pattern-based passwords also referred to as graphical passwords, involve the creation of a set of shapes, gestures, or patterns that are personalized by the user to authenticate him. As opposed to the next generation of alphanumeric passwords, which only contain characters, the pattern-based password involves a pattern or a sequence of lines on any graphical point-and-click interface, including a grid and touch screen. Such patterns can fall under connecting dots, dragging shapes, or swipe motions....

6. One-Time Passwords (OTP)

One-time passwords (OTPs) are passwords that are used on a one-off basis to ensure confirmation of a person’s identity and that can only be used for a single login or transaction. Compared to conventional passwords that are constant for a considerable amount of time, OTP delivers an additional layer of security where, for each attempted login, a new code would be generated. These channels include SMS, email, and maybe dedicated applications on mobile phones, tablets, or any other portable devices or hardware tokens. OTP, once utilized, lapses and cannot perhaps be utilized again, and this in some way limits the probability of unauthorized admittance even when the code has been compromised....
