Authenticator VS copyguard

I use a browser extension from https://authenticator.cc/

While I do not know whether its UX is similar, it does have a sync feature (but not cross-browser), an export feature, can backup its data to Google Drive, can store everything encrypted (but not by default), is recommended by at least one government website (SSS Employer Portal in the Philippines), and is there for a long time. Oh, and it also remembers which site each secret comes from, and hides others.

Currently, I'm using the Authenticator.cc browser extension on the same device for TOTP. However, I imagine security will eventually tighten and running authentication app/protocols on the same device that is logging in wont be an option.

The recommended extension is Authenticator, and it is compatible with Chrome, Firefox and Edge.

I've got a situation where we have a couple of staff that can't install MS authenticator; no smartphone. In some ways I'm jealous of them. Anyway, wife's company is of significant size and she passed off their docs on the issue and they use authenticator.cc browser extension for these situations. I tested it myself, and it works. It's just the raw OTP and not a number entry challenge.

For Windows, you really aren't going to find anything. The best I could find was a browser extension called Authenticator (no relation) but I cannot vouch for it.

Authenticator - for sites that have 2-factor authtificator codes turned on, like Amazon.

The code should be self-explanatory but if you want a more detailed explanation I recommend reading Stop Rashly Copying Commands From Websites by Louis Petrik, where I originally read about this exploit. It also includes an example and a link to a browser extension that I have created. More on that in a minute.
