is it possible to revert to the prior version on mac

Yes, 1PW8 is truly awful. Just another fine example of why the subscription model doesn't work for users. Companies lock you in, take your money with no accountability to delivering an ever improving product. Under the non sub pricing model, Agilebits would be suffering for foisting such a festering 💩 of a release on it's users and would have to work hard to make their users part with their hard earned cash ... but now the owners et al don't give a rats. They have the sub money in their pocket and the owners have cashed out, and checked out. Good news is there are plenty of better open source and passwordless solutions these days.
