I created an account a few months ago (post-Google announcement) and presumably I didn’t set a password when creating the account, or I linked my login with my Google Account. Not sure.
Now that Reader is dead, I got premium and downloaded the Android app to try it out.
The app prompted me for my password (which I didn’t know), and there was no “forgot password” option, so I just entered some random password to see if a “forgot password” option would appear.
To my surprise, I was logged in successfully. Regardless of the password entered.
That’s not good.
