Step 1 - Login to your Google account
Step 2 – Go to your account settings >> Manage your Google Account

Step 4 – Signing in to Google, select 2-Step Verification and turn this on
In this verification step Google double confirms that you are indeed an owner on the account and can make changes as radical as migrating inboxes to other systems. Make sure you have a (mobile) phone on hand, of someone who can also be reached (by Google) in case of security issues. This verification is done in 4 well explained steps.
Step 5 – completed 2-step verification
Now you have completed 2-Step verification process. That status changed to “ON”. Additionally a new element has been made available, called App Passwords.
Step 6 – add App – password
Going through this process you will create a unique password, allowing apps to connect. You need to enter this password in Customer Contact and it allows to connect the two applications (your Gmail account and CM.com Customer Contact). This password cannot be used by another or application, and has a short life time.
Step 7 – select the app and device
When you click on App-Passwords you will see all the app passwords already associated with this mail account. If this is the first time you won't see any app passwords.
In the select app dropdown box and choose: 'Other (Custom name)'
Enter an appropriate name that indicates this account is used for CM CustomerContact.
Step 8 - GENERATE button
Click the Generate button once you have entered a name you recognize in your Gmail account, as name to which you are connecting to. Now you will receive a Password. You will not be able to recall this password once the dialog has been closed! Copy the password and store it somewhere TEMPORARY and safe. This is the password you should use in Customer Contact on the email-channel.
