They are options in the meantime for the reset password process before the proper implementation in the application builder, but AFAIK they all includes an external automation tool (Make, n8n, zappier, …) for now because we need to send an email to the user. Is it a possibility for you?
@jrmi Thank you for confirming that external automation tools are the best way to achieve this for now. Would be more than happy to use (and pay) for one of them - the key being not too difficult to setup/implement
