When logged out of the Tomorrow app, you can see a button entitled “Sign-up or Log In.”
Tap that button and enter your mobile number associated with the account. On the next screen, enter the verification code sent to your phone as a text message. The next screen will ask for your password. While on this screen, click where it says “Forgot?”
An email will be sent to the address associated with your account and you will be asked to enter a new password. This link needs access to the app, so the email must be opened inside the phone in which the app is installed.
All passwords need to be a minimum of 8 characters. Press "Reset Password" when you are done typing your new password and it will be reset.
