How to Create a Custom Token for Authentication

TokenMaker.cs

var secretKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("KeyForSignInSecret@1234"));
var signinCredentials = new SigningCredentials(secretKey, SecurityAlgorithms.HmacSha256);

var tokeOptions = new JwtSecurityToken(
    issuer: url,
    audience: url,
    claims: new List<Claim>(),
    expires: DateTime.Now.AddMinutes(30),
    signingCredentials: signinCredentials
);

var tokenString = new JwtSecurityTokenHandler().WriteToken(tokeOptions);
