# No passwords. A code, and they are in.

Guests type their registered phone number or email, receive a one-time code and are in. You choose the channels per event: phone, email, or WhatsApp where your provider account is connected. GCOO Conclave 2026 accepted mobile numbers only; HCCB Partners Meet 2026 let international partners use email instead.

FAQ

## Common questions

Can international guests sign in?

Yes. They use email OTP where the event allows it, as HCCB Partners Meet 2026 and EEMA Connect did.

Can we show a privacy policy first?

Yes. An event can require guests to read and accept a privacy policy before the code is sent.

Can the code come on WhatsApp?

Yes, when your organisation’s WhatsApp provider account is connected and the template is approved.

Who decides who can sign in?

Your guest list, allowed domains or code rules. OTP proves the person owns the number or email; the list decides whether they get in.

## Choose how your guests sign in.

Tell us where your guests are. We will recommend the channels and show the sign-in on a phone.
