- Create a new address with a provider that doesn't ask for your phone number.
- Use a name unrelated to your own.
- Use aliases (a different address per service) so a leak in one place doesn't expose the rest.
- Never sign in to it on a shared computer or family tablet.
A second phone number
- eSIM or second SIM. Cleanest option, but it can show up in phone settings.
- Calling and messaging apps. Cheaper and easier to hide, but they're linked to an app account.
- Check local rules. Some countries require ID for SIM registration.
Keep them separate
- Different password from everything else, with a password manager.
- Don't link it to your main Apple, Google or social accounts.
- Don't use it for deliveries, loyalty cards or bookings.
FAQs
Do I need a second phone number?
Not essential. Telegram and Signal usernames mean you can avoid sharing one.
Which email provider is best?
One that doesn't require a phone number to sign up and supports aliases.
Can a second number be traced?
Yes, by your provider and potentially by authorities, so don't rely on it for anything illegal.
