If you are having trouble logging in to the QuantAQ Cloud, you can reset your password using the password reset form. Just fill in your email address and click Reset Password. Shortly after, you will receive an email with instructions on how to reset your password.
If you are still having problems (and you have checked to ensure the account recovery email didn't end up in your spam folder), then feel free to open a support ticket via the chat window in the bottom right corner of this page.
