The Dashboard is only functional once you click the activation link provided via email - this is a once off process that must be performed for each device/browser you use to login.
For convenience, we can remember you the next time you login, this simplifies the process.
If you are using a public device or feel uncomfortable with this feature, we recommend that you click 'Forget this Device'. Note, you will need to re-activate this device/browser the next time you login.
