Apps for community owners/mods

This may be a stupid question, but I am wondering how safe account info is on the PWAs and Lemmy apps seeing everything is in the infancy stage. Eventually, I would like to commit to and support whichever app fits my needs once they are well established. In the meantime, I am hesitant to use anything but the actual browser with my main account for fear of security issues that can compromise my community. Any thoughts from those who are knowledgeable on the topic are greatly appreciated.
