I personally think lemmy users for the most part are technical enough to get that based on the descriptions you two may add. Those communities already have followers right?
Photosync app to sync photos to a share. This app is awesome. I think to sync full photos it’s a one time 5$ payment. I’ve synced 70,000 photos and videos so I know it’s worth it.
I highly recommend getting them to access your sites over VPN not publicly then you don’t have to worry about this at all. For services that don’t have 2fa you can route the services from NPM to authentik. Then in authentik you have another password and can setup 2fa. Authentik is awesome.
You will be shocked how many times your sites are attacked by bots per day. Think five thousand plus.
backup your data and configs. Run docker. Run portainer to manage docker compose. Make a stack for each container and deploy. Use Nginx-proxy-manager to manage routing your domains. Open the ports on your router to NPM. If public run strong passwords and 2fa. If private but with local ssl you can use your local ip and it works the same, at least via cloudflare and npm.
