How to Set Up Two Factor Authentication Online

Set up two factor authentication on your accounts so a second step is needed to sign in besides your password.

Steps

1
Go to your account security settings
on the website or app you want to protect. Look for the "Security" or "Password" section.
2
Find the two factor authentication option
in the security menu. It is often called "Two Factor Authentication" or "Two Step Verification."
3
Choose your verification method
such as text message, authenticator app, or security key. Text messages work on any phone.
4
Scan the QR code
with an authenticator app if you chose that method. Apps like Google Authenticator or Authy work well.
5
Enter the code from your authenticator app
or text message to confirm it works. The account now requires a code each time you sign in.
