trying to understand the yellow triangle on bottom of a web page

Just curious about something

 

I went to update my yahoo password. So I log in and then I go to my account settings. I click to change password. So I'm taken to the page where you enter a new password and then confirm it.

So I complete the box with the new password and then I go to the confirm box and star entering the new password to confirm.

But I notice that as I'm re-typing in the confirmation of the passwaord, on the bottom left hand corner of the screen there is a small yellow triangle with and exclamation mark in the middle. I completed the confirmation of the password and entered and it sconfirmed password was changed

But I'm concerned about the yellow triangle thing

could that mean my password change was compromised?
