Authorization is an important component of modern applications since it ensures that only authorized users have access to specific resources or functionality. Without proper authorization, anyone could access sensitive data or execute actions they are not authorized to perform, potentially leading to security breaches or other difficulties.

In this post, we will look at the significance of authorization in modern applications, as well as some of the most common strategies and technologies for implementing it.

What is the significance of authorization?

According to one survey, over 6.85 million accounts are hacked each day, or 158 every second. According to a 2022 Google study, 52% of individuals use the same password on several websites. Furthermore, 13% of respondents acknowledged using the same password for everything.

Authorization is vital in modern apps for various reasons:

  1. Security: The most obvious purpose for adopting permission is to prevent unauthorized access to critical data or functionality. You may help to avoid security breaches and maintain the integrity of your application by ensuring that only authorized users have access to specified resources.
  2. Integrity: In addition to security, authorization is critical for ensuring an application’s integrity and reliability. If anyone can make modifications to the application or its data, tracking changes and ensuring that the application is running properly becomes significantly more challenging.
  3. Compliance: Depending on the nature of your application, you may be obliged to install specific authorization steps in order to meet rules or industry standards. Healthcare applications, for example, may be needed to include tight access restrictions in order to protect patient data.

Techniques for Authorization Implementation

To implement authorization in modern applications, a range of strategies and technologies can be employed. Among the most common approaches are:

  1. Role-Based Access Control (RBAC): RBAC is a popular authorization strategy that involves assigning users to specific roles and giving access to resources based on those roles. A user with the “admin” position, for example, may have access to all resources, but a user with the “user” role may only have access to a subset of resources.
  2. ACLs (Access Control Lists): An ACL is a set of permissions linked with a given resource. When a user attempts to access a resource, their permissions are checked against the ACL to see if they are authorized to do so.
  3. OAuth: OAuth is an open authorization standard that enables users to grant third-party applications access to their resources without exposing their passwords. OAuth is frequently used to enable users to log in to programs using social media or other external accounts.

Passwords are extremely important in the authorization procedure of modern applications. They are used to validate a user’s identity and ensure that only authorized users have access to specific resources or capabilities within an application.

There are several methods for storing a password in a database, including plain text, hashing, encryption, hash & salt, and so on. Plain text format is a less widely used option since attackers can immediately get the password if the database is stolen.

Cracking hashed passwords is tough since the original password requires a hash function of the guessed password. Although hashing may not totally secure the password, it does slow down the cracking process.

Passwords add to the importance of authorization in modern applications in numerous ways:

  1. Add an extra layer of security: Passwords are a popular way of authentication that aids in the prevention of unwanted access to sensitive information or resources. They serve as the initial line of protection against potential security issues like hacking or identity theft.
  2. Protect data confidentiality: Passwords help to ensure that sensitive information or resources are only accessible to authorized users. This helps to secure the data’s confidentiality and prevents unauthorized parties from accessing or misusing it.
  3. Make access control easier: Passwords can be used to restrict access to various resources or functionality within an application. An administrator, for example, may have a different password than a typical user, allowing them to access additional features or resources within the application.
  4. Enable accountability: By requiring users to authenticate using a password, access to resources and functionality within an application can be tracked and monitored more easily. This can aid in identifying potential security breaches or resource misuse.


Finally, the value of authorization in modern apps cannot be emphasized. It is an important component of a safe and reliable program, protecting both the application and its users. You can help to guard against security breaches and other difficulties by implementing proper authorization measures.
