Technology Basics in Plain English

Start with the essentials

Technology gets easier once a few core ideas click into place. Instead of memorizing definitions, these guides focus on the plain-English version of each concept plus a quick example you can picture. That makes the rest of the details far easier to absorb later.

If you only read a few, start with two-factor authentication and password managers — together they cover most of what keeps everyday accounts secure.
