Send password-reset links through Resend. You don't run a mail server — paste a Resend API key and a verified From address.
Resend needs a verified sending domain for the From address (add it in your Resend dashboard),
or use [email protected] for a first test. Get an API key at resend.com → API Keys.
Paste your key. It's stored encrypted and never shown again.
The address the reset link points to — usually this shop server's URL. Leave blank to use this PC.
