Yubico security key crashed. I replaced it. Some websites still ask for the crashed security key I do not have on all my Firefox devices
I registered a Yubico security key on Firefox. It crashed, so I sent it back for a refund. I bought another model, but do not want to use it. Websites continue to ask me the security key password and asks me to touch the security. I only used that key one time before it crashed. I can find no place to turn it off for Mozilla apps. Can you reset my account? How do I get websites that have skimpy security to stop asking for a Yubico security and they tell me Firefox requires it. I canceled one facebook account because they have very little security, but the one I used with the Yubico key one time will not let me login. The FB routines to recover a frozen account don't work. Please help Vance
Did you check your uninstall in control panel to remove its install? It also sounds like you might have to go to Yubico security key site to get support on this since this isn't coming from Firefox Browser.
I agree with what donthavecow posted (above).
You can possibly look at security.webauth prefs on the about:config page.
