What's the current method that works? I keep meaning to ditch Authy, and now that I'm moving to ProtonPass, it seems like a great time to finally finish this (Ente?)
I would still recommend switching to Vaultwarden. With Tailscale you don't have to expose it to the outside world.
Just keep a copy of the export somewhere else.
I like my export unencrypted and move it to a location that is encrypted.
