Hi ANDRE RIBEIRO,
Welcome to our forum!
Generally speaking, users who use no password will have much higher account security than normal users. If the account is still threatened in this case, there is a possibility that your device is a security risk (or you may have logged in to your account on some unfamiliar device), in which case hackers can successfully bypass the security information (e.g., sending a verification code to your authenticate) In this case, hackers can successfully bypass security information (such as sending a verification code to verify your identity) and change your password or other attacks directly on your logged-in account.
Therefore, we should not only take various approaches to account security (e.g. 2FA/no password) but also pay attention to whether the device used to log in is a security risk. It is suggested that you can run a virus check on your own device. Also, don't click on suspicious links easily when you are browsing the web or checking emails in general. If you need to log in to your account on someone else's device, try to use the privacy mode of your browser and log out of your account before you leave, so as to avoid leaving your private account information on an untrusted device!
Hope it helps.
