From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Banking 2FA can be done by SMS too, which is secure enough.
A world in which banking requires us to install spyware on our mobile computers is not a world we should accept.
Sms is not as secure as a 2FA app or the bank's own app. SMS verfification also costs money, so it will raise your monthly fees quite much if you wish to receive a text on every transaction.
As I said, SMS is secure enough without being the nightmare of a proprietary spyware app. As for fees, you have an American perspective, in most of the world SMS has been free to send for decades, and was always free to receive. The ideal solution is indeed a 2FA app, but those never took off.
I have a European perspective and here you need to pay per text message. Receiving is free, but the bank is charged and they put their charge on me, so they bill me for the messages, unfortunately. In the US SMS is free in most plans as I know.
My bank disagrees that SMS tan is secure enough 2FA and doesn't support it.
