New Alpaca sign in attempt

Hello, I keep getting this in my email. Is it a thing? I did click the link to report and it errored out. Kinda freaked me out a tick, thought what if phishing. Please advise

I seem to get these sometimes even when I’m the one signing in. They do have this at the bottom, though, which might be helpful:

If this sign-in was by you, you can follow this link to let us know

that link doesn’t work, errors out and is suspicious
