Apple asks for a trusted phone number when you create an Apple Account for two-factor security. You can use a number you control other than your own.
New Apple Accounts use two-factor authentication, and Apple needs at least one trusted phone number to send codes when a trusted device is not available. That is why sign-up asks for a number, even on a Mac or iPad.
| Option | Good to know |
|---|---|
| Your own number | Simplest and most reliable |
| A family member's number, with permission | They receive your codes, so choose someone you trust |
| A second SIM or eSIM | Good for a separate account you will keep |
| A temporary number | Not recommended: you need the number for future codes |
