I've been getting this too, authenticator prompts saying "logged in" and asking for confirmation, but no history whatsoever when I went to security to check.
It freaked me out the first time, I went through all the security settings I could find, but it was if it never happened.
I just ignored it the second time, but it's a bit unsettling, because the default authenticator flow also has the chance of accidentally hitting the right number.
Is that because it’s two digits?
No, because the default is to present you 3 numbers and asks you which your number is!
1 in 3 and easy to hit by mistake.
Shouldn't there be a button like "i didn't request this" or something? Why would you hit one of the buttons if you know the request is bogus?
You've never hit the wrong button by mistake on a phone touchscreen?
I can only envy your adroitness.
That's insane.
