And here is my AddAuthentication in Program cs

c#
builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
    .AddJwtBearer(options =>
    {
        options.TokenValidationParameters = new TokenValidationParameters
        {
            ValidateIssuerSigningKey = true,
            IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("JWT_SECRET")),

            ValidateIssuer = true,
            ValidIssuer = "https://localhost:5000/", // Your identity provider URL

            ValidateAudience = true,
            ValidAudience = "https://localhost:5001/", // Your resource/API URL

            ValidateLifetime = true
        };
    });

c#
builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
    .AddJwtBearer(options =>
    {
        options.TokenValidationParameters = new TokenValidationParameters
        {
            ValidateIssuerSigningKey = true,
            IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("JWT_SECRET")),

            ValidateIssuer = true,
            ValidIssuer = "https://localhost:5000/", // Your identity provider URL

            ValidateAudience = true,
            ValidAudience = "https://localhost:5001/", // Your resource/API URL

            ValidateLifetime = true
        };
    });

The token doesn't seem right to me and i can't decode it

Jimmacle•5mo ago

i don't believe there's a default implementation to make identity issue JWTs, all the examples i've seen online show implementing a custom controller

Okay thanks

You have to make service that will generate jwt for you based on needed claims
