Hello Clement,
I answered a similar question here.
This particular screen is called signup
and to update the password placeholder text, please make a PUT
request to the following Management API endpoint:
https://your_auth0_domain/api/v2/prompts/signup/custom-text/en
With the following payload:
{
"signup": {
"passwordPlaceholder": "Create a new password"
}
}
You can also do it via the Management API Explorer if you set up your Management API V2 Access Token.
Thanks,
Art
