Hi,
Maybe its an cool feature to create 3fa because I store as well, 2fa codes in there because I am kinda lazy, I have 2fa on my account now, but for extra security, 3fa maybe an good option like, an Authenticator app and Email code to get in.
You log in, not that often, just lock the Vault in the extension, or the Android app.
Kind Regards,
