For security reasons you can only access your Monese account from one device at a time. This means that when you change the phone used to access Monese this new device needs to first be authorised to access your account. The authorisation is done through the email you registered with us.
This is how it works. Download the Monese app to your new phone, open it and tap "Log in" and then enter the email address registered with your Monese account (do not start a new signup with Facebook or Email - that will end up as a duplicate account and will be closed). We will then send the device authorisation request to your email and once you have tapped or clicked on the "Approve phone" link in the email then you are good to go and can access your Monese account from your new device.
Not receiving the authorisation email?
Please make sure you remember which email address was originally used to create your Monese account and check that email inbox. If you haven’t yet configured that email on your new phone you can also approve the authorisation email from a computer.
