This is the best option. Love the app. But always remember to keep a backup of your tokens.

There is also ente.io authenticator app. It is available on fdroid. I think it supoorts cloud synchronisation as well.

Oh, also Firefox is the only mainstream browser on Android that supports installing extensions.

I have been using Firefox since the release of Firefox 57 aka Firefox Quantum in 2017. I love the browser and most of sites run well in firefox. But there have been a few cases where I had to use a chromium based browser.

Firefox + Ublock origin is a great and awesome combo.

I also use Firefox on android. It is okay, but I sometimes feel it is slow at loading some sites. But it is not a big deal.

You are a brave user, aren’t you?

What is the advantage of self hosting an NTP server?

After all, it just tells time

Try magic earth. It is good and privacy friendly.

Instead of using Gmaps. You can try

1. Organic Maps (Simple and clean app that just works)
2. OsmAnd (Full of great features but it may be too much for you). Supports realtime map update in pro version or the fdroid version.
3. Magic Earth but i think it is not foss
4. Mapy.cz uses Openstreetmap but it also does not seem to be foss. But the map is updated in real time.
