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.
I 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).
