Set up two-factor authentication for your accounts with Authy & Other 2FA Apps' Smartphones :: Gadget Hacks



If you have not received the memo, passwords are not enough protection for your online accounts. Even a long and complex password offers only one line of defense that can falter. Two-factor authentication adds an extra layer, strengthens your defense and reduces the risk of compromising your account.

These apps create a series of numbers called tokens that must be entered after signing in with your password to access your account. Since the app is on your phone, you need to know both your password and have access to your phone to sign in, making access difficult for others.

While there are several ways to implement two-factor authentication, 2FA apps provide a good balance between comfort and security. While SMS is not secure because messages can be intercepted and phone calls are not convenient, because you have to wait for an automated system to call your phone and read your code, 2FA apps will not compromise in any department. The token is much more difficult to intercept, but it remains as accessible as a text message.
