In that case it's the same as a reset-password flow.

In both cases it's good advice not to click the link unless you initiated the request. But with the auth token in the link, you don't need to login again, so the advice is still the same: don't login from a link in your email; clicking links is ok.

Clicking links from an email is still a bad idea in general because of at least two reasons:

1. If a target website (say important.com) sends poorly-configured CORS headers and has poorly configured cookies (I think), a 3rd-party website is able to send requests to important.com with the cookies of the user, if they're logged in there. This depends on important.com having done something wrong, but the result is as powerful as getting a password from the user. (This is called cross-site request forgery, CSRF.)

2. They might have a browser zero-day and get code execution access to your machine.

If you initiated the process that sent that email and the timing matches, and there's no other way than opening the link, that's that. But clicking links in emails is overall risky.

		1 is true, but this applies to all websites you visit (and their ads, supply chain, etc). Drawing a security boundary here means never executing attacker-controlled Javascript. Good luck! 2 is also true. But also, a zero day like that is a massive deal. That's the kind of exploit you can probably sell to some 3 letter agency for a bag. Worry about this if you're an extremely high-value target, the rest of us can sleep easy.
