MSMTP Gmail, username and password incorrect

I am trying to send emails using the php mail(); function. I have installed msmtp to allow me to use a gmail account. However whenever I try to send test email using msmtp then a destination email, the system freezed and I cannot write more commands.

This is the contents of ~/.msmtprc:

account gmail
tls on
tls_starttls on
tls_certcheck off
auth on
logfile ~/.msmtp.log
host smtp.gmail.com
port 587
user ****@gmail.com
from ****@gmail.com
password **********
account default : gmail

Also when it does sometimes work, I get an error which says bad credentials even though the details are correct, access for less secure apps is on and there is no 2-step verification.

If allowing less secure app doesn't work, you should consider 2FA.

Here is my working configuration:

account default
host smtp.gmail.com
port 587
from ""
tls on
tls_starttls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt
auth on
user "yourusername"
password "yourapppassword"
logfile ~/.msmtp.log
