 * I have been using your plugin successfully for over a year with Outlook 365. 
   Today, I went to set up a fallback connection for the occasional failed send,
   and I couldn’t get the plugin to send via Gmail. I get an authentication error
   every time.
 * I am following Google’s documentation: [https://support.google.com/a/answer/176600](https://support.google.com/a/answer/176600)
 * I use:
 * Connection Provider: Other SMTP
 * SMTP Host: smtp.gmail.com
 * Port: 587 (for TLS)
 * Encryption: TLS
 * Use Auto TLS: On
 * Authentication: On
 * SMTP Username & PW: My Gmail uname & pword

 * Hello [@nitrospectide](https://wordpress.org/support/users/nitrospectide/),
 * To Connect Gmail using other SMTP method use the guide below:
 * Turn on 2-factor authentication for your Google Account: [https://support.google.com/accounts/answer/185839?hl=en](https://support.google.com/accounts/answer/185839?hl=en)
   Visit My Account: [https://myaccount.google.com/](https://myaccount.google.com/)
 * Now we need to create An App password from here: [https://myaccount.google.com/u/3/apppasswords](https://myaccount.google.com/u/3/apppasswords)
   You may be asked to re-enter your Gmail password and then Create an app password
   with the type Other.
 * Now we can configure the Fluent SMTP, here you need to use Hostname: smtp.gmail.
   com, Security method as TLS, 587 as Port Email address as Sender and SMTP Username,
   and App password as SMTP password.
 * Please let me know the update.
 * Thank you.

 * I set up 2FA, and then the App password, but then for some strange reason, fluentSMTP
   would not let me save the new info. It kept giving me an error. After a bit, 
   it suddenly worked. Maybe the app password needed a few minutes to be fully active.
 * Thank you so much for the help!
