Failed to authenticate on SMTP server with username "[email protected]" using 3 possible authenticators. Authenticator LOGIN returned Expected response code 235 but got code "535", with message "535-5.7.8 Username and Password not accepted.

需要按下面的步骤去解决：
1、开启2步验证方式，通过这里：https://www.google.com/landing/2step/
2、为GMAIL设置一个单独的密码，通过这里：https://security.google.com/settings/security/apppasswords
3、把第二步里的密码设置到Laravel的.env文件里。
对于.env邮件的设置也要注意加密方式，下面的我的配置：
MAIL_MAILER=smtp MAIL_HOST=smtp.gmail.com MAIL_PORT=587 [email protected] MAIL_PASSWORD=独立密码 MAIL_ENCRYPTION=tls [email protected] MAIL_FROM_NAME="${APP_NAME}"
