I have two accounts: 1.
email@example.com and 2.
firstname.lastname@example.org. Both accounts have 2-factor authentication enabled. I am a Super Admin for #2. I would like to add account #2 G Suite work email to account #1.
I cannot get past the SMTP step (Send mail through your SMTP server).
Everything I read is related to allowing "less secure apps". However, our current setting is set to "Allow users to manage their access to less secure apps"
First, I don't understand how my personal Gmail is a "less secure app" and second I don't know where to go from here.
Has anyone successfully done this?
