What is two-factor authentication?
Two-factor authentication adds an extra layer of security to your account by combining what you already know (your log in details) with something you physically have access to (your mobile number, email, or smartphone via an authenticator app).
Two-factor authentication applies whenever you log in using a new device or browser. But if you prefer, you can set up two-factor authentication to apply every single time you log in. When you set this up, you can choose how you'd like to receive your one-time codes – by text, email or an authenticator app.
