As of March 31, 2019, you will need to have a confirmed email to use Parsec. We're doing this to protect your account. Whenever you log in from a new IP address, you're going to receive an email that looks like this:
Only after confirming your login attempt will you be able to access Parsec. If you enable two-factor authentication in your Parsec settings, we'll stop asking you to confirm your login via email. Since we're going to rely on your email address being accurate to give you access to your account, we need you to confirm that you didn't use a fake account to sign up for Parsec. Confirming your email prepares you to unlock your login attempts in the future.
