Password Reset Email Send - check for email existence first

[stoyan.kalinov.ext]

So at the moment on our NextJS project the thing we are doing is that on the Universal Login page → The login template we have an link for “Forget Password”, which shows one input where the user can enter the email on which he want to reset his password.

The code to send the email for password reset is simple:

But doesn’t matter if the email exist in the database, the email will be just sent.

So after a bit of research in the forum I have found some topics about that.

For example:

Any check if user/email exists with auth0.js?

I have searched the api for reference in auth-0.js for any reference on check if exists, the closest thing I found was checksession, but really wanted to ask if anyone knows!

and

Auth0 forgot password email check

when i clicked on don’t remmeber my password it will ask me for email to reset password but there is no way to check when i enter an email that this email exists in database or not. as in current scenario it will send link to any email i am inserting without checking there that it is valid email or not. so i want to build this functionality when inserting email in forgot password textbox

So the reason for that is to not expose which emails are registered in the database for security reasons.

So as I explained on the first sentence what we are doing in our project, is there a way to actually show an error message under the input if SOME user tries to reset password for an email which doesn’t exist ?
Or such thing is not possible with our requirements ?
