About Protect IID
What is Protect IID?
Protect IID is a privacy solution that enables you to create single-use email addresses for each online service you sign up for. By using a catch-all email address on your own domain, it ensures attackers cannot predict or link your email activity across services—boosting your online anonymity.
Who is it for?
Ideal for privacy-conscious individuals, frequent online shoppers, and anyone tired of spam or data breaches. It is not for users who want a managed alias service without owning a domain—Protect IID requires you to buy and configure your own domain.
Real use cases
Use Protect IID to sign up for newsletters, free trials, or forums without exposing your real email. Combine with a password manager and two-factor authentication for a layered defense against phishing and identity theft.
Key features
- Single-use email generation — Create a unique email address for every account, making it impossible for attackers to link your services.
- Anonymous domain masking — Use a non-personalised domain to hide your name and personal data from sign-up forms.
- Catch-all email forwarding — Automatically forward all incoming messages to your primary inbox without manual setup.
- Domain owner privacy — Your domain registration details are protected by most registrars, adding an extra layer of anonymity.
- Flexible domain choice — Buy a cheap, dedicated domain exclusively for email aliases to keep your main domain separate.
- Password manager compatible — Store your single-use addresses and strong passwords together in tools like LastPass or 1Password.
