We have moved to a predominantly password-less log-in process, using a Magic Link that sends an email to you to create a secure log in. Once you have created a session on the app you will remain logged in with your preferred biometric security providing a quick log in experience.
If you wish you can set up or change your app PIN when logged in. This is available using the profile menu at the top right of the app, and the "Settings" option.
You will continue to have the choice of Magic Link or PIN log in.
