Synchronize Google contacts with Evolution while using 2 Step authentication

Once you start using 2 step authentication in your Google account, it becomes a little bit more complicated to have the different services in Evolution to talk to your account. (see procedure at google) Emails and Calendar is straightforward (using the generated passcode from the google site. 

For your address book you can't add or change your password within Evolution. But no worries, the following workaround is not that hard. 

1. open "passwords and keys" in the Ubuntu applications menu
2. open the Passwords tab
3. find the google:// entries for your google contacts
4. open that entry or entries and expand the password dropdown at the bottom
5. reset or enter your new password (generated by Google for the 2 step authentication)
