For some seniors, their texting skills -- or lack thereof -- are locking them out of their Social Security accounts because of a new security measure added this week.

It's a security practice most of us are familiar with. When you enter your username and password, a text message with a code is sent to your phone. You then enter that code on the website to get access to your account.

In the case of the Social Security website, a new code is required each time you log in because it expires after 10 minutes. So if you don't have a cellphone that receives texts, you can no longer log in to your account.

This seems to be a problem for a lot of people who've taken issue with the change.
