Protecting Your Online Accounts with Two-Factor Authentication
About Two-Factor Authentication
What is two-factor authentication? Many websites and online services offer two-factor authentication (2FA), also referred to as multi-factor authentication (MFA), two-step authentication, or 'added security verification'. 2FA is an added security feature that helps protect users’ accounts and confidential information. 2FA makes it more difficult for unauthorized users to gain access by strengthening the sign-in process with the addition of an extra verification of identity, in addition to username and password. 2FA adds another step by requiring the user to submit something unique and additional that only they would have, before access to the account is granted. In addition to something you know (your username and PIN, password, or pattern), access would require something you have (e.g., ATM card swipe, or one-time code (generated by an app on your smartphone or texted to your phone), or something you are (fingerprint or voice).
Currently, most online services that offer 2FA use a one-time code. We strongly recommend that you use 2FA for your online accounts, especially the critical ones (i.e. financial accounts). You should always read the backup options of 2FA for any service in the event of losing or having to reset your smartphone or account.
Traveling with Two-Factor Authentication
If you are traveling and plan to use applications or accounts that require two-factor authentication, be sure to have a way to authenticate your login and configure authentication methods prior to traveling. Note that if use call or text for authentication, your mobile device will often require service at your destination(s). Additionally, if you use an office phone method (if available), an alternative method will be required while traveling. Many, not all, mobile app methods do not require an internet connection. If necessary, check with the support staff before traveling.
