Thanks for asking. There's a "forgot password" link on the login screen in the app. (see image beside when login).
In addition to that, there are a couple other options on the web (but not in the app):
Please Reset Your Password For your security, we are strengthening our password requirements and as a result, your existing password has been disabled.
.
Please enter your email and click "Continue" below to send a password reset message to the email associated with your account. This email will contain a link to reset your password that will expire within 24 hours.
