Oh nice ! Thanks for the explanation. Is this type of authentication supported by many apps and services ? Can it completely replace an authenticator app on a phone ?

I was curious about the number of passengers carried by rail, so I looked at the wikipedia page. The US is 12th with 533 million passengers in 2019, which I find surprisingly low when compared to the population/size of this country. In France, same year, there was 1880 million passengers. I don’t think the rail infrastructure is well developed in the US, probably to the benefit of car infrastructure.

I use perlite to improve the drainage of the soil of my houseplants, I did not know it was used in construction and it was such a big market. So I was a little confused.
