Oh damn, this is more of a headache than I expected.

I’ll take a look at termux and syncthing-tray when I have time for that.
I already had a cursory glance, and syncthing-tray seems to have a lot of caveats and syncthing on termux is not quite the gui-app I wanted. But at least there are some apps even if they aren’t ideal yet.

OpenSuse Slowroll (rolling release with constant updates plus an update burst every two months)

• Prefer rolling release over fixed release.
• I do like OpenSuse in general.
• I install a lot of packages and want to stay up to date (security & GUI notifications). With OpenSuse Tumbleweed I have to install a couple gigabytes of updates every week. It’s not ideal for me.
• Too impatient to wait for the proper release of Slowroll.

How numbers are pronounced.
In German the number 185 is pronounced as “hundred-five-and-eighty” (hundertfünfundachtzig), the digits are not spoken in order of their magnitude.
Not terrible, not great.

The security of a fully random password depends on the number of available symbols (alphabet) and the length.
The strength of the password is simply symbolcount^length.

For a conventional password the symbols/alphabet are characters, numbers and special characters.
For a mnemonic the symbols are simply full words and the “alphabet” is a list with a couple thousand words.

Mnemonic passwords are secure because of their large alphabet, and easy to remember because of the lower length (in symbols) and because human brains are good at coming up with associations (usually stories) for random words.
If you want to generate your own mnemonic password you can try diceware.
With diceware you roll a few dice to select random words from a list.
