I'm often logged into a non-public Network, where I was given a user name and password for the captive portal to gain internet access.
In Safari on my MacBook, I made a bookmark for the portal page and stored the password. Now when I connect to the network, I can open the bookmark, click on the key symbol to fill my credentials and log in.
But since a few weeks (or months? I don't remember if it is connected to some update I made) about a second after filling the saved password, Safari suggests to use some cyptic password like it does when you register for some service. It's a nice feature when you are asked to invent a new password, but completely weird when logging in with a stored password (which I can't even change!).
Now I always need to click, that I don't want that suggested password and select the stored password a second time. How can I stop this annoying "feature"?
