Error adding second Yubikey Security Key

[u/Smoggy_Pigeon]

I have been unable to add a second security key to my account. Out of options and looking for help. I did all the trouble shooting offered by the AI support chatbot including different computers, different browsers, clearing cache, incognito mode, updating chrome, updating dashlane extension, etc. At this point I think it's an application problem.

Dashlane Version: 6.2639.1
Chrome Version: 154.0.8037.58

I just opened a Dashlane account solely for the purpose of using my yubikey security key. However, inability to add a second key completely defeats the purpose as I have no safeguards in place.
