Basically every bank blocks Tor and many even block VPNs. Also, Tor Browser is not particularly secure. It's been designed for fingerprinting resistance and network anonymity through the Tor network. The Tor Browser is based on Firefox, which lacks many important security features like site isolation, Control Flow Integrity or any meaningful sandboxing. I absolutely hate Google and their monopolistic business practices, but Chromium is by far the most secure browser. Especially when it's running on a secure mobile operating system. GrapheneOS goes even further than Android and deploys a hardened memory allocator (which was actually ported from OpenBSD), which significantly reduces the risk for memory coruption. On the newest generation of mobile SOCs (ARMv9), GrapheneOS enables memory tagging by default. Again, find me a desktop platform with MTE. This once again proves my point that mobile devices are simply more secure. Every single piece of hardware and software in your phone has been built with a strong focus of security.

Or, better, use monero.

I absolutely agree on this one. Look at the Lemmy instance I'm on. I'm a big fan of Monero, but unfortunately there aren't many places that accept XMR.

No, Tails doesn't solve this issue at all. It's built for maximum anonymity, not security. It also uses Tor for all connections, which will get your bank account locked immediately. Qubes is a good option for security, but it's way too complicated for most users. Stop making up some random shit and accept that mobile devices running modern operating systems are reasonably secure and definitely more secure than your ordinary desktop.

Americans have something even worse: SMS

I'm talking about the security model of the platform, not the way you use your devices. If you do your online banking in a browser on your computer and your system gets infected with malware, that malware can access all the files on your computer. Including application data of your browser. It can access your cookies, which your bank's website uses to store your login information. Such an attack is impossible on a mobile device, since apps can only access their own data, and inter-process communication is heavily restricted. Additionally, mobile operating systems like Android have complex permission systems, as well as kernel-based mandatory access control like SELinux/SE for Android. Your typical desktop OS has none of that. Android also has a strong implementation of Verified Boot, which makes sure that malware can't persist on your system partition, even after your device gets infected.

GrapheneOS even significantly improves Android's already pretty good security model.

Is it worse than in other European countries?

Oh sorry, my bad. I meant it's not some third party app that has to be installed with root privileges, but rather just a well integrated part of the system, which uses Android's permission system to deny internet access.

I remember having used Shotcut many years ago

If the machines are on the same network, try LocalSend

Switzerland seems like a nice place

GrapheneOS has a built in Firewall that doesn't require root privileges. Also, you don't trust the GrapheneOS devs who arguably create one of the most secure operating systems on the planet, which is open source and can be verified by everyone, but you trust Calyx devs who regularly go months without releasing any Android security patches and include highly privileged third party apps in their operating system. Makes a lot of sense.

CalyxOS has pretty bad security. They install F-Droid and microG with root privileges, don't release updates regularly and lack many security features of GrapheneOS.
