You can reset your password by clicking "Forgot your password?" on the Log in page. This will send an email to reset your password to the email address associated with your account.
If you are logged in your Poll Everywhere account already but don't remember your current password to change your password, first log out of your account, then reset your password on the login page as described above.
Helpful tip: If you attempted a password reset but did not receive a reset email from Poll Everywhere, it may be because the email was caught in your spam or junk folder. To correct this, you can whitelist this email address: firstname.lastname@example.org. Afterwards, attempt the password reset again.
