I started to use Dashlane with Brave for my passwords. Safari on Monterey allows you to export them in a csv file, making the transfer way easier than before.Tricky. Been using Safari since ever and all set up with passwords etc. However the last iteration is woefully bad for me, I use firefox for general stuff and back to safari for login/shopping or whatever.
Not tried Brave, might give it a go.
One hopes they fix Safari soon. Even the Preview is hobbled for me.
