Test an email without 'Less Secure App Access'

Totally understand your concern about "Less Secure App Access". Here are a few options to test email sending in CodeIgniter without enabling it:

1. Local Testing with Fake SMTP Server:

Use a library like "PHPMailer" with a local fake SMTP server like "MailCatcher" or "FakeSMTP". This simulates sending emails without actually sending them anywhere. Great for initial testing and development.
2. Use a Dedicated SMTP Service:

Consider signing up for a free or paid service like SendGrid, Mailgun, or Amazon SES. They offer secure SMTP access without needing "Less Secure App Access". They usually have simple integrations for CodeIgniter too.
3. Implement Email Templates (No Sending):

Focus on building well-formatted email templates in your CodeIgniter backend without attempting to send them. This tests the content and structure without involving external servers.
4. Test with a Different Email Provider:

If you have another email provider (e.g., Yahoo, Outlook), check if they offer SMTP access without requiring similar security compromises. Test cautiously with a dedicated email address for this purpose.
Remember, using "Less Secure App Access" isn't ideal, and these alternatives let you test and develop your email functionality safely and securely. Good luck!
