jwt token expiration time (asp.net core)

Question

I\'d like to increase the lifetime of JWT token but I can\'t.

I tried googling the matter and found references to JwtBearerOptions.TokenValidationParameters.ClockS

Answer 1

expiration value undefined in token descriptor.

var tokenDescriptor = new SecurityTokenDescriptor
{
   Issuer = _config.GetValidIssuer(),
   Audience = _config.GetValidAudience(),
   SigningCredentials = new SigningCredentials(_config.GetSymmetricSecurityKey(), SecurityAlgorithms.HmacSha256),
   Subject = new ClaimsIdentity(new[]
   {
      new Claim(ClaimTypes.Name, user.UserName),
      new Claim(ClaimTypes.NameIdentifier, user.Id.ToString())
   }),

   // expiration time here...
   Expiration = _config.GetExpiration() // etc
};
