Can a wordpress admin see my failed Login attempts?

First of all I am a careful (maybe paranoid) guy. I tried to login into a WordPress account few days ago and didn´t noticed it was the “Admin” login. I even notice that I can login via Twitch … but that was too late!

If it’s not your account you should notify them! If you can get in who else might be in there doing bad things?

Back to my story. If I try to login via “www.xyz.com/wp-login.php” -> Is it possible that the actuall Admin will get my Data (Username/Mail/Password)?

If it’s a standard install, no, but from what you’ve said it isn’t. So possibly yes, if code has been installed, there’s no way of knowing without reading the code or looking at which plugins are installed.

Thankfull, you follow the advice to use strong passwords, and to never reuse passwords.
