I want to be logged in so I can do most things on Reddit like post and comment. I want it to be a web frontend rather than an app because I keep many tabs on Reddit open in my browser while doing research on things (like digital privacy for instance!). I did some searching and didn’t find any currently working frontends with login support.
Unfortunately, since the API change, Reddit blocks VPNs even on old Reddit.
EDIT: If you must visit reddit via VPN, consider using sh.reddit.com. It only supports the new layout though.
