SimpleLogin: what it is and how to use it

SimpleLogin is an open-source email alias service, now a Proton product. One alias per site forwards to your real inbox without revealing it, and if a sign-up leaks you switch off just that address.

How do you use SimpleLogin?

  1. Open simplelogin.io with the VPN on, checking the domain in the address bar.
  2. Create the account using your private email (Proton Mail or Tuta) or an email from your crypto identity, never your personal one.
  3. Create one alias per service, naming each after the service rather than after you (for example, the exchange's name).
  4. Use the alias at sign-up: the site never sees your real email, and you can reply from the alias without exposing the destination inbox.
  5. Keep the alias list in your password manager and switch off any alias that leaks or starts receiving spam.
  6. Protect the destination inbox with a strong password and 2FA, since everything sent through the aliases lands there.

What are the limits and cautions?

  • The alias protects the address, not the destination inbox: if someone breaks into the inbox the aliases forward to, they see everything that arrived through all of them. That inbox must be private and have 2FA.
  • The free plan covers up to 10 aliases; unlimited aliases, custom domains and PGP are on the paid plan. Paying with a card tied to your name creates a link.
