In my last post I talked about choosing a strong password. You may read about that here<\/a>.<\/p>\n

Even doing so does not guarantee that your account is secure.<\/p>\n

There are mainly 3 types of authentication methods.<\/p>\n

    \n
  1. \n

    Something you know<\/h3>\n<\/li>\n<\/ol>\n

    A username and password fall into this category.<\/p>\n

      \n
    1. \n

      Something you have<\/h3>\n<\/li>\n<\/ol>\n

      Everyone has a mobile phone. This is a personal device which is always in our possession and has a SIM card with a mobile number.<\/p>\n

      Banks and various other companies have started to use the mobile number as authentication by sending an OTP (One Time Password) by SMS. A new OTP is generated every time we try to login.<\/p>\n

      Companies like Microsoft and Google provide an \u201cAuthenticator App\u201d which links your mobile phone to your account. Think of this like an OTP sent on the Internet to your mobile phone.<\/p>\n

      Google has also made it even simpler. You just need the Gmail App. So now let\u2019s say you are trying to sign in on another device, you will be prompted and asked to tap “Allow” right on your mobile, and that\u2019s it!<\/p>\n

      The Apple ID is protected by two-factor authentication automatically! If you try to sign in with the Apple ID and password on www.icloud.com<\/a> or on a new Apple device you will get a pop-up on your existing device asking you to tap \u201cAllow\u201d followed by an OTP which needs to be entered into the new device.<\/p>\n

        \n
      1. \n

        Something you are<\/h3>\n<\/li>\n<\/ol>\n

        These include various biometric techniques. For example, fingerprints (used in most mobile phones) and face scans (such as in iPhone X).<\/p>\n

        Do I need this?<\/h2>\n

        Yes!<\/p>\n

        Credit cards already have two-factor-authentication. You provide the name, number, expiration date and CVV after which you receive an OTP to complete the transaction.<\/p>\n

        Having all the three methods would be a bit excessive, but I would recommend having a two-factor-authentication. Password + OTP is the most common.<\/p>\n
