There are several limitations or restrictions of using Basic Auth with NGINX Ingress Controller:

1. Limited security: Basic Auth is a simple authentication mechanism that is vulnerable to brute force attacks and credential stuffing. It is not recommended for securing critical applications or services.

2. Static user credentials: Basic Auth uses static user credentials that are hardcoded in the NGINX configuration files or secrets. This makes it difficult to manage users and their credentials, especially when dealing with a large number of users.

3. Lack of granularity: Basic Auth only allows for a single username and password for accessing a particular endpoint or application. It does not provide fine-grained access control based on user roles or permissions.

4. Lack of flexibility: Basic Auth is a static authentication mechanism that cannot be customized or extended easily. It cannot be integrated with other authentication providers or mechanisms.

5. Lack of scalability: Basic Auth does not scale well, especially when dealing with a large number of users or requests. It can slow down the NGINX server and reduce performance.
