It adds an extra layer of protection that\u2062 requires you \u2062to prove who\u2063 you\u2062 claim to be, beyond just a username and password. This is\u2063 done by\u2063 having \u2064a code sent \u200bto \u2062your phone, which\u2062 you then enter to gain access.<\/p>\n<p>Using two-factor authentication is a great way to protect your online accounts as it makes it much\u2062 harder for a hacker to access your account, even if they have \u2062your username and password. However, it is \u2062important to weigh the pros and \u2062cons of security measures. There have been cases\u200b of SMS texts being intercepted, so it \u200dis best to also use other two-factor authentication options, such as:<\/p>\n<ul>\n<li><strong>Authenticator App:<\/strong> \u2063 this is a \u2064dedicated 2FA \u2062app\u200b installed on your phone, and\u2063 usually requires you to\u200b enter in \u200ca \u2064changing 6-digit code. \u2063<\/li>\n<li><strong>Biometric Authentication:<\/strong> this\u2064 technology uses physical \u200dor behavior traits like fingerprints, face, voice or iris\u2063 of\u2064 an eye to verify\u200b your identity.<\/li>\n<\/ul>\n<p>At the end of the\u2062 day, the most important thing is\u200d to ensure your accounts are \u200cprotected, no matter the method used.<\/p>\n<h2 id=\"2-the-risks-of-using-sms-2fa\"><span class=\"ez-toc-section\" id=\"2_The_%E2%81%A2Risks%E2%80%8C_of_Using%E2%81%A2_SMS%E2%81%A4_2FA\"><\/span>2.
