JWT Bearer tokens: what it is, how to configure?

JWT (JSON Web Token) is a compact, URL-safe token format used for authentication.

✅ Configure JWT auth:

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)

.AddJwtBearer(options => {

options.TokenValidationParameters = new

TokenValidationParameters {

ValidateIssuer = true,

ValidateAudience = true,

ValidateLifetime = true,

ValidateIssuerSigningKey = true,

IssuerSigningKey = new

SymmetricSecurityKey(Encoding.UTF8.GetBytes("your-secret"))

});

Use [Authorize] to secure endpoints.
