The current mail is not very helpful.
Today I got such a mail from email@example.com The last time I accessed wikipedia.beta.wmflabs.org was on August 21th, at least according to my browsers history.
I would like to see a little bit more information:
- The date / time of this login
- the IP-address
- the user agent string of the browser
Usually mail is sent immediate, but mail is not a real time system, some mailer may delay sending the mail, so it may take some time.
When I see the IP-address, I could check if this is my current address, so everything is fine – when the IP-address is from some different country I would know if this is a real problem.
With the user agent string I could find out which device caused this alert.
Currently all that information is missing. It is not very useful.
