'Use of oauth 2.0

I have written a free-to-use psychotherapy website. It uses my gmail address to send each user a password. I have therefore set my gmail account to work with 'less secure apps'. That setting will no longer be available from May so i need to use oauth 2.0 to make my website into a secure app. But when i read about it, it states that the website user needs to grant access to the google account. This confuses me for two reasons

  1. it's MY account, not the site user's account
  2. I am horribly ignorant about internet systems I'd be very grateful for any advice or comments but please could you express it in the simplest language possible?
