Recently Mozilla started requiring 2FA for their AMO site used to publish addons. I have a few private addons that I develop and use, nothing big yet, but I really didn't want to link anything up with 2FA over SMS and I'm also trying to reduce my "Google footprint" so instead I selected their only alternative that doesn't use a centralized third party.
It was a bit complex, but I eventually got Keepass to generate the TOTP codes which so far are pretty awesome.
