Just found an old #sdcard of my former #android phone. It is formated - I guess - as #adoptable storage. I remembered that there might be an interesting picture on it.

I do not know whether the Sony Z1 I used that time does still work, but I'll try to recover it with this knowledge I wrote down 5 years ago: https://xdaforums.com/t/howto-replace-device-and-keep-sdcard-with-adoptable-storage.3913789/post-79200875 .

Story is probably not new: using a #Librem5 (linux mobile) and everybody insists on using WhatsApp. I didn't care. But all activities the kids want to take part: #WhatsApp.

I could try to evangelize all these football trainers, parents representatives at schools, parents of friends to use something that I'm able to use on my linux phone, but I can't: lack of energy, lack of time, lack of alternatives with the same feature set and stability.

Got out an old Sony Z1 running #CarbonROM. Really old software. Got an so far unused SIM. I used Aurora Store from F-Droid to install WhatsApp from the Google Store on that Android. Registered to WhatsApp and it worked fine sending one test message that never arrived, because the other side didn't have my phone number in their contacts (I guess).

I installed #conduit as a #matrix server on my #yunohost and put mautrix-whatsapp #bridge on its own system using the latest docker image following the documentation to get a minimum configuration running.

Yeah, works. Coupled WhatsApp on the Android Z1 with the bridge and send two test messages resulting in This account can no longer use WhatsApp due to spam shown on the #Android device.

Is that most likely because of my 10+ years device + rooted + Magisk + fake google app store #Aurora or is it something others are experiencing when trying to use the bridge with of the shelf devices, too?

My plan has been to run an independent phone number for WhatsApp on a device that only has contacts for WhatsApp in its phone book and make it available to family members through matrix.

Our participation in society relies in many aspects on the goodwill of a few monopolistic companies that we depend on. They write the rules which device (Android or iOS) and which software (only their own doing whatever they program it to do) we're supposed to use. They train the algorithms that can cut you off our participation.

I wouldn't care the least. I'd even smile when reading this thinking that it's exactly what people supporting companies like facebook/whatsapp deserve. But if the participation of my kids in society is at stake (and not my own which I well can organize without any messenger) it makes me sad.

If a service wants you to download #GoogleAuthenticator for #Android or #iOS to activate mandatory 2nd authentication factor:

• It's the same as using <space> nitropy nk3 secrets add-otp --protect-with-pin --touch-button --digits-str 6 --kind totp paloalto <seed> with your #Nitrokey 3 - don't forget to check the command history to delete the key from there in case the leading space of the nitropy-command didn't stop your shell from saving the command to history.
• If they then show you a QR you're supposed to scan with your always online, known to be unsecure, sending everything to the cloud device there's ususally a button for can't scan that'll show you the seed
• If #javascript on the page then makes it impossible to copy that seed at least in firefox there's right click/inspect (q) which you can use to have a quick look at the source of the element to copy the seed from the source (think about how secure your clipboard is and whether you need to delete the seed afterwards from it. Big mess: clipboard history writing to disk possibly without full disk encryption).
• Otherwise - if there's no way to get a text view of the seed - take a screenshot of the qr, save it, and use zbarimg <screenshot-file> to get the text reading from the qr
