A user can create a new account by entering an email address and password.
When the app gives someone trouble like this it is often one of two things. The first thing to check is to be sure you used the sign UP button and not the sign in button first.
If you've already did that please reset your password and then try to copy and paste the new password into the password field. The second biggest reason for people having trouble is that they have reset their password and a zero looks like an O when the password arrives via email. Ensure you copy and paste this new password in and sign in should go well.
Once signed in you can go to the menu and at the bottom of the menu is your user name. There you can enter a new password of your choosing.
