If you have 2 Factor Authentication (2FA) enabled in your Google Workspace account, you have to create an App Password to be able to connect your mailbox to MassMailer Inboxing Service.
First we need to make sure 2FA is enabled on your account
If it's well enabled, we guide you to create an App Password
Once it's done, you can connect your mailbox to MassMailer Inboxing Service.
Step 1 : Make sure your Google Workplace account has 2 Factor Authentication (2FA) enabled
Go to your Google mailbox, click on the top right account and then > Manage your Google Account
In the left menu, click on Security then Secure account.
It brings you to an overview of the security protocols you've enabled. If you see 2-Step Verification here, that means Two Factor Authentication is enabled. (even if you have the yellow color like below).
Once you've confirmed that 2FA is enabled, please go to Step 2.
If you don't see 2-Step Verification like in the screenshot, it means 2FA is disabled. To connect a Google Workspace account without 2FA, please follow this guide instead.
Step 2 : Create an App Password
Go to the App Passwords page. You may be asked to sign in to your Google Account.
In the Select App dropdown, select Other.
In the Select Device dropdown, select Other.
You can name this password "MassMailer" or any other name that you would prefer.
Click on Generate.
You should see your generated app password displayed.
Step 3 : Use your generated App Password when connecting your mailbox to MassMailer Inboxing Service
Provide First Name, Last Name, Email Account, App Password details to MassMailer to set up your Inboxing Service.
