Sign-in codes by email

Haiya has no passwords. When you sign in with your email, Haiya emails you a six-digit code that you type to finish signing in. Nobody can sign in with your email address without the code from your inbox.

If something goes wrong

When a step fails, Haiya shows a short message with what to do. Find the message in the first column.

Messages you may see, why they appear and what to do
What you see	Why	What to do
The code has not arrived	Email can be slow, or the address has a typo.	Check your spam folder, then press Resend code, or Use a different email address.
Haiya asks you to wait before trying again	Too many wrong codes were typed.	Wait a few minutes, then ask for a new code.
You did not try to sign in, but got a code	Someone typed your address on the sign-in screen.	Do not share the code. Without it they cannot sign in. Check Active sessions.

Can I use an authenticator app or a text message instead?

No. Haiya sends sign-in codes by email only. On iPhone and Android you can add a second lock to the app itself: in Privacy & security, App lock sets a six-digit passcode, with Face ID or your phone’s biometrics where it has them.

Google or Apple confirms it’s you, so Haiya doesn’t email a code. There is one exception: the first time a Google or Apple account joins an existing Haiya account or invite with an address Google or Apple doesn’t manage, such as a work address on a personal Google account, Haiya emails a six-digit code to that address once.

Each teammate has their own email and their own code, so Haiya always knows who sent a message or changed a customer. See how the shared team inbox works.
