Is it possible that the use of the Wikipedia app for Android (beta) triggers a failed login attempt -- sometimes?
The claim is vague and I cannot reproduce it, but I have been suspecting for a while that there is a connection between the notifications of login failed attempts and my use of this app. Using the app doesn't trigger the notification always, but I would swear that whe I get that notification, I have been using the app (which I do sporadically).
To bring a bit more of vagueness, a possible factor to consider is the app user changing language when using the search. Again, I know it might not make much sense, but is the feeling I have. I will keep paying attention and reporting any facts or thoughts.
If someone is able to look at logs, User:QuimGil received a failed login notification on 2017-10-21 just a few minutes after doing a search to Catalan Wikipedia from the Android app (beta).
From merged task:
A bug report from wikimedia.org, https://www.mediawiki.org/wiki/Topic:U12oukyg4w1h6tnx
"I have the Wikipedia mobile app installed on both my phone and my tablet (both Android devices), and I have seen a significant uptick in the last couple of months of notifications of a multitude of failed login attempts that seem to coincide with my having opened the app, perhaps with a less-than-reliable internet connection. Is this a known issue?"
I asked him to confirm whether these are failed attempt notifications, or successful from an unfamiliar device. He says he's getting failed notices, but successful seems like it would make more sense...
