Bearer [tokens](https://answers.mindstick.com/qa/92537/what-are-tokens) are commonly used in various scenarios where secure authentication and authorization are required. They are especially well-suited for certain use cases due to their simplicity and efficiency. Here are some scenarios in which bearer tokens are commonly used and the reasons why they are a good choice:

**API Access**:

- Bearer tokens are frequently used to secure access to APIs. They are an efficient way for clients, such as web or mobile applications, to authenticate and obtain authorized access to resources exposed via an API. Bearer tokens simplify the authentication process and work well with stateless APIs.

**Single Sign-On (SSO)**:

- Bearer tokens are an essential component of Single Sign-On (SSO) systems. They enable users to log in once and then use a bearer token to access multiple related services and applications without the need to re-enter their credentials.

**Mobile App Authentication**:

- Bearer tokens are a secure way to authenticate mobile applications. They allow applications to obtain access to resources, like user data, without exposing the user's credentials, enhancing security.

**Cross-Origin Resource Sharing (CORS)**:

- In web applications, bearer tokens are used to handle cross-origin requests securely. They enable client-side code running in a web browser to make authenticated requests to APIs on different domains while adhering to the same-origin policy.

**Resource Protection**:

- Bearer tokens are employed to protect and control access to specific resources, such as files, documents, or data. They ensure that only authorized users or applications can access these resources.

**Microservices Authentication**:

- In microservices architectures, bearer tokens are often used for authentication and authorization between services. They enable communication between services while ensuring that only authorized services can access others.

**IoT Device Security**:

- Bearer tokens can be used to secure communication between Internet of Things (IoT) devices and cloud services. Each device can use a bearer token to authenticate and transmit data securely.

**Temporary Access**:

- Bearer tokens are suitable for scenarios where users need to grant temporary access to their resources. Users can share a token with specific expiration dates to allow others access for a limited time.

**Password Reset and Email Confirmation**:

- Bearer tokens play a role in the process of resetting passwords or confirming email addresses. Users receive a token in their email, and they use it to confirm their identity and perform the desired action.

**Two-Factor Authentication (2FA)**:

- Bearer tokens can be part of a two-factor authentication process, where users need to provide something they know (e.g., a password) and something they have (the bearer token) for increased security.

Bearer tokens are favored in these scenarios due to their simplicity, ease of implementation, and suitability for stateless authentication. They provide a streamlined way to manage authentication and authorization in modern applications and services while maintaining security and efficiency.
