Resend Passwordless OTP

I am signup user using passwordless SMS (otp) is there any way to resend OTP again.

Hi @vishwakarma.anchal19 ,

Thank you for posting on the Auth0 Community!

If I understand correctly, you want to know how to resend the OTP to a user to log into an App configured with Passwordless authentication.

Could you please go to Authentication → Passwordless → click on SMS → under the Try Tab, enter the user’s phone number? Then the user will receive a new OTP to log into the App.

Hope it helps!

This is manual efforts. Is there a way, if users clicks on my button for resending the OTP and they receive it.
Situation : User did not receive the OTP in some time and then they can just click on any button from mobile or web and then they receive the OTP to login.

Hi @ritesh.rai ,

Welcome to the Auth0 Community!

To accomplish this, could you please try configuring a submit button to call the Authentication API endpoint /passwordless/start, and let us know how it goes? Thanks!

Thank you! that means we need to start authentication and in that case new OTP will sent. My query was, is there a way to resend the same OTP.
Is there any API that we can use to resending the same OTP.


I found this topic talking about sending the same OTP. Hope this helps!

No, here same otp for Email and sms have been discussed.


I am not aware of any API can resend the same OTP. Sending a unique OTP is for security purpose. Hitting the endpoint again will restart the process.
