I just tried it out and I’m amazed. It looks and feels just like 1Password, my absolute favorite password manager (before I switched to Bitwarden, because 1Password is proprietary and pretty expensive)

I definitely recommend it

There’s an Android app, but it’s not being developed any more https://github.com/android-password-store/Android-Password-Store

There’s an iOS app as well https://mssun.github.io/passforios/

They have a list with all the clients and other tools on their website

If you’re on a time crunch, go ahead and use network namespaces under network manager to set up something like what you want as another user suggested.

Is there a way to do this without NetworkManager?

I’d go for netdata, if you just want to monitor the health of your entire Linux server, and Uptime Kuma for checking individual services. You can also set it up, so that you receive a notification if a service goes down, e.g. over ntfy or Pushover. See the documentation for Uptime Kuma push notifications https://github.com/louislam/uptime-kuma/wiki/Notification-Methods

I’m assuming you use this app to access your passwords on android? https://f-droid.org/en/packages/dev.msfjarvis.aps/
