A 4 digit PIN can be set within your account for logging in purposes, instead of using your full email address and password.
This will allow you to access your account with more ease.
After logging in a prompt will appear which you can select to set this. Once set, when you click to “Log In” you will be prompted for the PIN.
You can also enable the PIN login at any time from within your logged in account, under the “My Details” tab.
