change account access less secure apps

to keep google apps users' accounts secure, may block less secure apps accessing google apps accounts. google apps user, see "password incorrect" error when trying sign in. if case, have 2 options:

1. option 1: upgrade more secure app uses date security measures. google products, gmail, use latest security measures.

2. option 2: change settings allow less secure apps access account. don't recommend option because might make easier break account. if want allow access anyway, follow these steps:

   2.1. go "less secure apps" section in account

   2.2. next "access less secure apps," select turn on. (note google apps users: setting hidden if administrator has locked less secure app account access.)

if still can't sign in account, "password incorrect" error might caused different reason.

update:

add error reporting top of file(s) right after opening php tag example <?php error_reporting(e_all); ini_set('display_errors', 1);

and enable debug on phpmailer

$mail->smtpdebug  = 1; // enables smtp debug information (for testing)                        // 1 = errors , messages                        // 2 = messages 

to see if yields anything.
