Two-factor authentication (also called 2FA) adds a second layer of protection to your Nowistay account. Once it is on, signing in from a new device requires both your password and a 6-digit code sent to your email address. Even if someone gets hold of your password, they cannot access your account, your properties or your guests' details without that code.
With two-factor authentication enabled, your password alone is no longer enough to sign in. After you enter your email and password, Nowistay emails you a one-time 6-digit verification code. You type the code on the sign-in screen, and only then is access granted. The code changes every time and expires after 10 minutes, so it cannot be reused.
The feature is optional, free, and available on every Nowistay account.
The card now shows the Enabled badge. This confirmation step also makes sure you really have access to your mailbox, so you can never lock yourself out by mistake.

A few useful details:
On the verification screen, tick Don't ask again on this device for 30 days before clicking Verify. Nowistay then remembers the browser you are using: for the next 30 days, you sign in there with just your password. Any new device or browser still asks for a code, which is exactly the point: only you can approve it.
Turning two-factor authentication off (or off and back on) clears all remembered devices, so each one is asked for a code again at its next sign-in.
Your account is then protected by your password only. You can re-enable the feature at any time, the same way you first activated it.
