2FB integrates directly with your browser, which allows it to automatically verify that a website is authentic before providing a 2FA code during login. Never worry about getting tricked into providing a 2FA code to a phishing website again!
2FB automatically generates and submits 2FA codes during the login process in your browser. No need to interact with your phone, which could easily distract you with some unrelated notifications! No more manually transcribing 2FA codes from your phone. No more copy/paste.
2FB notifies you anytime that you log into a website that supports 2FA and you don't have it enabled. It is important to stay informed as your existing third party services add new security features that you might not be aware of and as you sign up for new third party services.
