How OTP delivery works for your end users

One-Time Passwords are delivered by email, not SMS. Here's what that means for your onboarding flow and support scripting.

Email only

SMS OTP

Summary: One-Time Passwords are delivered to end users via email. There's no SMS or push-notification channel for OTP delivery today — email is the only path.

①

What this means for your onboarding flow

Since email is the only OTP channel, the accuracy of the email address you collect during onboarding directly determines whether your end user can complete authentication at all:

●

A typo'd or unreachable email address blocks login, not just notifications

●

Don't design a UX flow that assumes SMS as a fallback channel — it doesn't exist today

●

Most "can't log in" or "didn't get my code" tickets trace back to spam filtering or a wrong email on file, not a system issue

Important

Equip your first-line support to check spam folders and verify the email on file before escalating "missing OTP" tickets to Swype — it resolves the majority of these cases without needing our involvement.
