Try Proxmox or some other hyperisor. Also learn about cloud images and cloud-init. It’ll take seconds to spin up a new machine from scratch. And you can experiment as much as you want and break stuff. You can even create an isolated network within Proxmox itself with Onpnense and nested Proxmox to mess around with networking.
I don’t touch my home prod when I want to test some new service.
Bitwarden is a very convenient password manager for an average computer user. It’s very straightforward and easy to use.
I can see some bias here of the people who say “o, just use KeePass and sync the database over some cloud provider”. What if there are conflicts? How do they deal with them? I can figure it our but most people I know, won’t.
Even the password manager concept is a complicated concept to grasp for many people (that I know). And I can recommend them Bitwarden because it’s relatively easy, but KeePass with sync? Maybe, if I commit to actively help them with it.
P.S. I’ve convinced several people to try out Linux, and they are willing to learn it, but even if they just need to use a browser, they struggle sometimes. I can’t imagine them syncing the KeePass database.
I installed it after breaking my Debian several times. Now, I just need to make sure I don’t bork my Proxmox :)
But that’s easy because I have nested proxmox with an isolated network backed by OPNsense. So I can break it as much as I’d like.
