When I try to get updates I see an Authentication required dialog box. I tried the password I set-up during installation but is fails. What is the authentication?

  • Be specific. If you ask a vague question, you’ll get a vague answer. But if you give us details and context, we can provide a useful answer. How do I ask a good question?

  • By any chance did you change your keyboard layout after the installation to something different used during the installation? Dec 19, 2018 at 8:21

If you are sure you've forgotten your password (check caps lock, typos etc) you can try and reset it using recovery mode as per https://askubuntu.com/questions/24006/how-do-i-reset-a-lost-administrative-password. Should be similar for elementary OS.
