Switch emulator - which one? (safe code?)

In the past, I've used yuzu at my desktop to emulate switch games and it worked quite nice. Given that I own a nice android phone, I was thinking about doing it on my phone nowadays. I know yuzu has been taken down and that there are a lot of forks now. Is any of them really safe to use? If so, could someone recommend me one?

Also, I do have prod keys from an older for an older version of yuzu. Will that work?

Thanks in advance for any help!
