It's open source would be too much of a hassle to set up in your case, the cloud version you can integrate in a couple of minutes and has a generous free tier.

My employer (FusionAuth) has the same feature in our community edition and it's quite popular: https://fusionauth.io/docs/v1/tech/passwordless/magic-links

It is glorious from the user perspective, but there are actually some subtleties from the implementation perspective that caused us some grief.

First of all, you have email configuration and deliverability. The answer is to outsource it to a provider like Sendgrid, SES, or Mailgun.

Then, there's anti phishing email software which can expire one time tokens as it probes to prevent phishing attacks. More on how we built around that here: https://github.com/FusionAuth/fusionauth-issues/issues/629
