if you have brave, bitwarden and bitwarden extension, and your bitwarden is setup for your yubikey as webauth 2fa
(you also need the extension set to “Not remember your 2fa” so it prompts each time you login…
the latest version of brave now throws this error
if you have it set to “remember you” the only way i found to clear that is to uninstall/reinstall the extension
this works fine with 1.47.186 and older… but 1.48.158 breaks it (but appears to only break bitwarden extension, other webauth sites appear fine)
