Browsers are starting to offer basic password
management tools as well. They work in a
pinch but aren’t good enough overall.
Investing in a proper password manager is
well worth it (especially because many
services offer a free tier).

- ENABLE TWO-FACTOR
AUTHENTICATION
Most major services now offer a two-factor
authentication feature, especially if they handle
more sensitive personal data. Turn it on
whenever you can. If a hacker does somehow
manage to gain access to your login
information, 2FA can still save your bacon.
Two-factor authentication requires you to
confirm your account two ways before you’re
able to log in: with something you know and
with something you have. The “something
you know” is your username and password.
The “something you have” comes courtesy of
an authorized tool that’s in your possession.
Usually, 2FA requires you to input a code
that’s sent to you via text message or email
when you try to log in on a device for the first
time, or to grab a code from a supported 2FA
app, or to connect a security device devoted
to account authentication. The exact method
varies by service, and many offer several 2FA
options. Without that code, hackers can’t
break into your account even if they have your
login information.
Our two-factor authentication guide (go.

more deeply and includes our picks for the
best 2FA apps and hardware.- STAY SAFE
