Apple two-factor authentication sends a six-digit code to your trusted devices or trusted number when you sign in to iCloud on something new.
When you sign in to your Apple Account on a new device or on iCloud.com, Apple shows a code on your other Apple devices. If none are available, it sends the code by text or call to a trusted phone number. You enter the code to finish signing in.
Most Apple Accounts created in recent years already have it on, and it cannot be turned off for them.
| Problem | Fix |
|---|---|
| No prompt on other devices | Make sure they are signed in, online and unlocked |
| Text not arriving | Choose Didn't get a code and pick a call instead |
| No trusted device or number | Use account recovery from iforgot.apple.com |
On a signed-in iPhone, open Settings › [your name] › Sign-In & Security › Get Verification Code. This works even offline.
Apple lets you add a recovery contact, someone you trust who can help you get back in, and an optional recovery key. With a recovery key set, Apple cannot reset your account without it, so store it safely.
You can add physical security keys in Sign-In & Security. Once added, they replace six-digit codes on new devices, which protects against phishing.

On iCloud for Windows or iCloud.com in a browser, you enter the code shown on your Apple devices just as you would on a new iPhone. You can choose to trust the browser so you are not asked each time on that computer.
Some older devices cannot show a prompt. On those, add the six-digit code to the end of your password when you sign in.
To your trusted Apple devices, or by text or call to a trusted number.
For most accounts, no.
