So what would be a good 2FA method then? Next-level 2FA: meet U2F For example, slow rollouts of updates, a lack of passcode protection, and no database backup make the app vulnerable to more sophisticated attacks. While an improvement from 2FA by SMS, the Google Authenticator app comes with some shortcomings of its own. Once this remote attack is successful, this leaves any sensitive information in your account within the attacker’s grasp. SIM Swapping is a common form of social engineering explicitly designed to circumvent user 2FA using SMS verification. Most common versions of 2FA take place through a mobile phone, either through getting a code through SMS or e-mail or by using an application giving you a 2FA code such as Google Authenticator or Authy. Along with your usual login ID and password, 2FA asks users to enter another specific set of information that only the user could know. Two-factor authentication (2FA) is an added layer of security to accounts where sensitive data or crypto assets are held.
Common 2FA methods and their shortcomings Fortunately, there is an easy way to increase their security: We’d like to introduce you to Universal Second Factor (U2F) authentication – a form of two-factor authentication hosted by the FIDO Alliance. This can have drastic consequences – from sensitive data being taken to money being stolen through it.
More and more we read about e-mail accounts being hacked or our precious passwords being available online.
The more we expect to be able to access our money from anywhere, the more important U2F is for our security. Ledger devices can be used as U2F thanks to the FIDO app, drastically increasing the protection of your digital accounts. U2F is the next level in 2FA, where a specialized device needs to be connected in order to login. Traditional 2FA methods do have their shortcomings still and can fall prey to attacks.
To increase the protection of your accounts (such as e-mail), two-factor authentication (2FA) was introduced.
