Kaedah ini berkesan untuk saya, anda boleh mencuba ini:

1. Mula-mula pergi ke Pengurusan Akaun Google anda, kemudian Keselamatan.
2. Pastikan pengesahan 2 langkah anda didayakan.
3. Kemudian pergi ke Kata Laluan Apl.
4. Pilih Lain dalam menu lungsur Pilih Apl dan namakannya mengikut pilihan anda.
5. Kemudian klik "Jana" dan Google akan memberikan kata laluan kepada anda. Pastikan anda menyalinnya dan menyimpannya di tempat lain.
6. Jangan gunakan kata laluan Akaun Google sebenar anda dalam tetapan PHPMailer, sebaliknya gunakan kata laluan yang baru anda hasilkan.

  /*
  To use this new method of PHPMailer follow the following steps on 
  ubuntu:
Step 1: Install Composer
    $   sudo apt update
        sudo apt install php-cli unzip
    $   cd ~
    $   curl -sS https://getcomposer.org/installer -o /tmp/composer-setup.php
    $   HASH=`curl -sS https://composer.github.io/installer.sig`
    $   php -r "if (hash_file('SHA384', '/tmp/composer-setup.php') === '$HASH') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
        Output: Installer verified
    **Note**: If the output says Installer corrupt, you’ll need to repeat the download and verification process until you have a verified installer.
*   The following command will download and install Composer as a system-wide command named composer, under /usr/local/bin:
$   sudo php /tmp/composer-setup.php --install-dir=/usr/local/bin --filename=composer
Output
All settings correct for using Composer
Downloading...
Composer (version 2.3.5) successfully installed to: /usr/local/bin/composer
Use it: php /usr/local/bin/composer
To test your installation, run:
$   composer

Langkah 2: Pergi ke direktori akar tapak web dan jalankan arahan berikut

$   composer require phpmailer/phpmailer
