Authenticator App - Lemmy.one

What authenticator app do you use? How do you backup? Any open source self hosted options?

I use andOTP but I didn't realize it wasn't in active development. I might give aegis a try. I have a yubikey and once I get a second one I may move everything to that.
there's a fork of andOTP, here's the github repo: andOTPPlus. aegis is also awesome, i use it.
