The response code was expected to be 250, but instead 535 was received, and the message was "535-5.7.8 Username and password not accepted"

Question

I recently encountered a SwiftMail error while trying to send mail through gmail. Expected response code 250 but received code "535" with message "535-5.7.8 Username and password not accepted. I tried sending the mail through my gmail and google thought I was spam (probably because I requested too quickly) and they sent me an email saying that my account was accessed and I told them that I did it myself. I was able to send emails without issue, only now I have this problem. Here is mine

I had the same problem, changing my gmail password solved the problem, also don't forget to enable Insecure Applications on your gmail account

I researched on the internet and some of the answers included enabling "Lower App Access" and "Unlocking gmail verification code" but unfortunately didn't work for me Worked until I found two-step verification.

What I did was:

To enable two-step verification on Google, click here
To create an application password for system use, click here
I selected Other (custom name) and clicked Generate
Go into my laravel environment file and edit it

MAIL_USERNAME=talentscoutphil@gmail.com

MAIL_PASSWORD=Generated password
Restarted my Apache server and it worked again.

This is my solution. I created this solution to at least save others from wasting time looking for possible answers.
