Local only set-up question

Hello everyone, setting up vaultwarden in docker on ubuntu server 22.04 using portainer. My settings are:
Image
- vaultwarden/server:latest
- Manual network port publishing
- host 80 → container 80
- Volumes
- /data
- Restart Policy
- Unless stopped

I can connect with http with no problem and can create the user and set everything up, however before doing so i wanted to double check that i understand correctly.

  • as i have not published the same port on my firewall it should be save to use http, correct?
  • will i be able to sync the vault with mobile devices?

As it tradition to say - i am new to homelab and wanted to make sure that i am not missing smth.
P.S i tried googling, but mostly for local set up people can’t get smth to work or access the web-gui, for me it works out of the box, so I am more concerned if i understand correctly what it is doing.
Thanks!

Port 80 is HTTP, and will only work via localhost.
If you want to access it abroad, you need to use HTTPS.

hey, thanks a lot for the reply!
just to be sure - so it’s secure and safe to use if i want it to be accessible local only?
