How can I disable auto-login?

Hello Everybody,

If I click on sign-in after a single click I'm logged in. This means the login-details get stored somewhere.
I don't like that. How can I DISable this super-fully-automated login?
I want to type in username and password each time.

best regards Stefan

This happens when you are still logged in to your arduino.cc account. If you log out of that account then you will need to do a normal log in to access either account.

That information is stored in your browser.

If I delete all my browser cookies (i'm using Chrome) my autologin capability disappears.
