heylogin frees you of your passwords. That does not mean your login is insecure. You are protected by 2-factor-authentication. The first factor is your phone. You decide, whether you unlock it with your fingerprint, your face or your PIN - just like you do everyday. Your accounts are also secured by 2 factors: Your phone, something you own, your fingerprint or face, something you are, or your PIN, something you know.
