Major security bug in Safari allowing preview of saved passwords without any protection at all.
Safari saved passwords preview is protected but this can be prevented and worst case is if you have autocomplete on - just open web inspector and change input type="password" to input type="text" the content of the input is revealed . The input HAS to empty itself on type change thus keeping the data safe. Already told [email protected] but no response received. Hopefully this will be fixed soon.
