Create application specific passwords

How to let a device sign in when it cannot prompt you for a two-step code.

An application passcode is a separate password for one device or program. It exists because some mail programs cannot ask you for a two-step code, so they cannot sign in once two-step authentication is switched on. Set up two-step authentication first: see setting up two-step authentication.

Each passcode covers one device, so revoking one leaves the rest working. That is the point of issuing them per device rather than sharing one.

Step 1

Login to Webmail with your current password

Step 2

Go to Preferences -> Accounts -> Primary Account Settings and
Go to 'Applications' above Password Recovery Account Settings:

Step 3

Click the 'Add Application Code' button

Step 4

Enter a name for your device in the 'Application Name:' field

Step 5

Click on the 'Next' button

Step 6

Make a note of the Application Passcode

When using your device for the first time, you will need to enter this passcode to sign in to Webmail, without needing to use two-step authentication. 

Step 7

Click on the 'Close' button

The device has now been added
