I cannot setup my Gmail account. It says id or password is wrong. I suspect it is because I have 2 factor authentication setup to text me when I access from a new application or PC. I guess I could turn off 2 factor, but really don't want to do that.
You can generate a one-time app password within your Google account settings and keep using 2fa for all other accesses. See: https://myaccount.google.com/apppasswords
If it's about geary mail, you may need to give permission.
Log into your gmail account https://myaccount.google.com/lesssecureapps Turn it on. You should get the notification for your 2 factor authentication.
