This is a follow up to this question asking about what should be displayed when a user enters a wrong password.
Here is my current design: when logging into a website if the user enters a wrong username/password, the page displays beneath the password field "wrong username/password" in red. The conses of the linked to question was to keep the "wrong username/password" message there, which I'm fine with. What I'm concerned about is what will happen if the user enters a wrong password again? I don't want the message to blink and I'm not sure how to show the user that the second password is also wrong and it's not just the page is hanging. If it changes colour I was thinking of changing it to yellow for 0.25 seconds. If this is the approach should the first time the message is displayed the colour is different initially or does the colour only change after the first wrong login?
EDIT: I forgot to mention the password field is cleared if it wrong. I'm not sure if this enough of an indicator though, is it?
