            new Claim(JwtRegisteredClaimNames.Sub, user.DisplayName),
            new Claim(JwtRegisteredClaimNames.Email, user.Email),
            new Claim(JwtRegisteredClaimNames.Birthdate, user.BirthDate.ToString()),
            new Claim(JwtRegisteredClaimNames.Jti, Guid.NewGuid().ToString())
        };

        var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_config["Jwt:Key"]));
        var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);

        var token = new JwtSecurityToken(_config["Jwt:Issuer"],
          _config["Jwt:Issuer"],
          claims,
