Do you still use two-factor authentication (2FA) to secure your online accounts? You should switch to a physical security key instead. You might be thinking why? Security keys add an extra layer of protection to your accounts. When you use 2FA authentication to log into your account, such as Gmail, a one time password is sent to your phone. You enter this password to sign to your account. Since you should have access to your phone to get the required code (one factor) and the sign-in credentials (the second factor) to verify your identity to ensure that only you are the original owner of this account.
