I have two accounts: 1. personal@gmail.com and 2. work@company.com. 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?

This question came from our site for computer enthusiasts and power users.

  • The reason your personal email is a "less secure app" is because you cannot put in a 2-factor code to send SMTP messages. – Moshe Katz Jan 30 '17 at 3:55

    Have you tried setting up an app specific password for SMTP? – Vidar S. Ramdal Jan 30 '17 at 11:17

I detailed how to do this step-by-step in a medium post: https://medium.com/@csaba.apagyi/using-g-suite-gmail-from-your-personal-gmail-explained-step-by-step-6509187a710e

As for SMTP:

  • Enable “Allow less secure apps to access account” option for users in G Suite admin
  • Allow less secure apps in the G Suite account
  • Ensure POP and SMTP are not disabled in G Suite admin
  • Configure SMTP in the main Gmail account

You can find links to support pages for each step in the post linked above.

  • Great, this worked. You will also have to enable "Less secure app access" in the specific G Suite account – Gianfranco P. Jun 11 at 10:34

    It's one of the steps above :) "Allow less secure apps in the G Suite account" – thisismydesign Jun 11 at 12:00

Really you should be using two factor auth and then assigning app passwords to things like gmail send through g-suite SMTP. This avoids downgrading security for less secure apps (which, I think, google is phasing out anyway)
