Security that gets out of your way

The protections big platforms use, on an account you control.

  • Passkeys first

    Sign in with your face, fingerprint or device PIN. There is nothing to phish and nothing to forget.

  • Two-step verification

    Add an authenticator app with backup codes, or go passkey-only and switch passwords off entirely.

  • Bring your own sign-in

    Link your Google, Apple, Facebook or Steam account. Its email does not have to match your Gate.haus one.

  • You decide what apps see

    Every app asks before it gets your details. Review and remove access whenever you like.

  • More than one email

    Keep personal and work addresses on one account. Only your primary address is shared with apps.

  • Alerts that matter

    Hear about new sign-ins and security changes as they happen, so nothing goes unnoticed.
