Hi Neyra,

Welcome to the Community! 🥳

This post should help you, it’s not phone number but it’s the same concept. 🙂

> Hi @Michael, For the reference - you might find this thread useful, especially later posts: [Sign up without email](https://forum.adalo.com/t/sign-up-without-email/3910) Also, there is a video related to this question: [Adalo Experiments: how to allow users sign up with username - YouTube](https://youtu.be/vAtLX_Rl_18) As for me, when implementing username sign-up, I’ve decided to fill in the email field as well (automatically, with the same value as username), to keep the user uniqueness. I guess that only email field is checked automatically for that.
