Gmail setup stopped working after the update

[aspectvm]

I had a setup for the gmail smtp, like so:

debug: true
mailer:
  engine: smtp
  smtp:
    server: smtp.gmail.com
    port: 587
    user: '[email protected]'
    password: 'xxxx xxxx xxxx xxxx'

It was working fine for my both sites (I have a multisite setup) until the most recent update to 4.1.0. version. Now, it is logging this error:

"Failed to authenticate on SMTP server with username "[email protected]" using the following authenticators: "LOGIN", "PLAIN", "XOAUTH2". Authenticator "LOGIN" returned "Expected response code "235" but got code "535", with message "535-5.7.8 Username and Password not accepted. For more information, go to 535 5.7.8 https://support.google.com/mail/?p=BadCredentials a640c23a62f3a-a6c805c59a2sm133747166b.50 - gsmtp".". Authenticator "PLAIN" returned "Expected response code "235" but got code "535", with message "535-5.7.8 Username and Password not accepted.

[] []"

I have tested the same credentials with phpMailer in a separate script, and it works no problem. This plugin (for me, at least) only works with Outlook currently, but not with Gmail.

What version did you update from?

The previous one 4.0.4. I also tried sending email with Gmail using CLI test command. Same situation.
