The fact that Firefox isn’t listed as a browser alternative but Brave is throws any credibility that this article might have straight into the garbage.

Suggesting Brave anything throws its credibility into the shitter, much less multiple times in multiple categories.

BTW, any authenticator app works when it tells you to use one. They all use a standard, so it doesn’t matter which one you use.

Eh, it’s a little more nuanced than that, there’re more standards for MFA code generation than just TOTP.

And even within the TOTP standard, there are options to adjust the code generation (timing, hash algorithm, # of characters in the generated code, etc.) that not all clients are going to support or will be user-configureable. Blizzard’s Battle.net MFA is a good example of that.

If the code is just your basic 6-digit HMAC/SHA1 30-second code, yeah, odds are almost 100% that your client of choice will support it, but anything other than that I wouldn’t automatically assume that it’s going to work.

The only answer is Ublock Origin.

Aside from that, you can do adblocking for your entire network and everything on it via Pi-hole. It requires no modification for the devices on your network and will work for literally any device connected to it.

If you combine those two, the odds of seeing any ad anywhere isn’t zero, but it is close enough to zero to effectively be zero.
