Google doesn't support third party app access anymore.
Because of this members of my forum will not be able to receive email notifications anymore. Is there any way around this, I'm not quite sure if this is specific to non workspace accounts or anything google related either. Is there any way around this. I really don't want to have to change the forum email address to something that isn't google since it's too much of an inconvenience.
Gmail CAN do it if you set up 2FA and then set it up as a device with a special password they dictate. I had to do that last week at work, for a copier that was emailing scans via gmail. It works fine again, after going through the steps above.
