Unable to access my Optus account on android mobile because forgotten PIN. How do I change PIN please.
you can delete the app and reinstall and it will prompt to reset the pin aslong as your remember your password to your account
You don't need to reinstall the app.
Just log into the app using your My Account login and change PIN. When asked to confirm current pin, just login with the My Account details again, then it will let you choose a new PIN.
