Go to General, scroll down to the bottom, and select Transfer or Reset iPhone.

Frequently Asked Questions
Why does Microsoft keep asking for two-step verification on my trusted iPhone?
This usually happens if your browser is set to block or clear cookies automatically, if you are using private browsing mode, or if there is a glitch in the device's privacy settings preventing the trusted device token from being saved.
What happens when I reset Location & Privacy on my iPhone?
Resetting Location & Privacy will not delete any personal data or apps. It simply clears all the permissions you have previously granted to apps (such as access to your camera, microphone, and location). You will be prompted to grant these permissions again as you use your apps.
Can I have multiple trusted devices on one Microsoft account?
Yes, you can register multiple trusted devices to your Microsoft account. However, you should regularly review your account's security dashboard to remove old or unused devices to maintain optimal security.
