Enable MFA everywhere

How do you enable multi-factor-authentication (MFA) on your accounts?

Phishing and reused passwords are how most personal accounts fall. MFA will not fix a bad password habit alone - it raises the cost of the next attempt.

Multi-factor authentication means proving more than one thing:

  • Something you know - password
  • Something you have - phone, authenticator app, security key
  • Something you are - fingerprint or face

SMS is the weakest common second factor. Still better than password alone. App codes and passkeys are stronger. Many services only prompt MFA on a new device or place - small friction for a real lift.

Enable it wherever the option exists. Prefer passkeys when offered. I wrote why complexity charts miss the point in Does password complexity matter?.
