Gmail disable “less secure app access” for an email that setup for scan to email

Hi

I have got Brother Printer MFC9330CDW, I tried to setup scan to email following

https://help.brother-usa.com/app/an...ow-to-configure-and-use-scan-to-e-mail-server

Email that I have used for setup is : MCF9330CDWhome@gmail.com (not real email)

What I have to do under gmail setting I have to enable(on) : “less secure app access”

Everything working fine but after couple of days “less secure app access” option gets disabled (off)

What should I do to prevent Gmail disable that ? if not do we have alternative solution ?

Thanks
