Using Gmail - making my application secure

Arik123 has asked for the wisdom of the Perl Monks concerning the following question:

Hi, monks!

I wrote an application that uses Gmail (IMAP and SMTP), using modules I found on CPAN (Email::Send::SMTP::Gmail and Net::IMAP::Simple::SSL). It works... only that Gmail complains that my application is insecure, and wants me to configure my account to allow access for insecure applications.

Is it possible wo access Gmail in a way it'll be happy? to write a secure application in Perl?

Thank you very much!

Google calls all applications "insecure" that don't use its two-factor authentication. If you want to keep using standards like IMAP and SMTP to access email with Gmail, you will have to put up with them calling this insecure.	[reply]

Do you mean there's a way to send/receive mail via Gmail without using SMTP/IMAP?	[reply]

Yes, you'd have to use the google APIs to send the mssage which involves an OAuth login. Good Day, Dean	[reply]

You can set application specific passwords for applications to use SMTP. I suspect this applies to IMAP, but my success has varied in getting email this way due to rate limiting. A more reliable approach I've found is using fetchmail with gmail to get the mail. If you wish to send many emails (even with a "gmail" address), AWS' Simple Email Service (SES) has proven super reliabe for me and is super cheap.	[reply]
