That’s amazing

Now I’m curious: Could something similar also be done for VRAM?

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?
