Sign in

to 4AB — one identity across every product

or sign in using

No passkey on this device? Create one — it never leaves the device.

Three ways in, one rule

  • A code to your phone or email — proves the address itself.
  • A provider you already use — Google, Facebook, Microsoft, Zoho.
  • A passkey — your face, fingerprint or PIN, checked by your own device. Nothing to remember and nothing to steal.

Whichever you pick, the browser is handed a short token that says nothing about you, and this server exchanges it for the identity. A page script can see that someone signed in; only the server learns who.

Some providers cannot prove an email address. Those sign-ins let you look around; email and WhatsApp still have to be confirmed before anything is bought, changed or sent.
