 Hi, I'm Frank. Today I want to show you how to share very confidential secret files with NextCloud using a feature called video verification. This is very innovative and exists only in NextCloud. Okay, basic sharing is of course very easy. Let's say we have this PDF here that you want to share with someone. You can always press this share button here, then the sidebar opens and then you can share with people. For example, I can type in the name of someone. Here, Matthias is already in my address book, so I already have auto completion here. I press here and then it spins for a second and now it's configured and you can press this button here and you can select a few more options. So next slide has, of course, a lot of options to protect the data. For example, you can protect this share with an additional password. You can set an expiration date and you can also add an additional note that the recipients get when he gets an email with this share link. The problem is, let's say I'm a bank and I want to make sure that only Matthias has access to this PDF. No one else, not the kid who is playing with the smartphone, not the spouse, not the sis admin, not a hacker who has access to the PC of Matthias, maybe only Matthias himself and this is very easy. So for this case, we have an innovative new feature and this is called video verification. You can activate it by pressing here, password protect by talk. You press here and then you can type in a password. You can choose a password. Let's say, secret one, two, three, four in this case, of course, in reality, it should be a little bit more secure, obviously. And then it's already set. And then the share link is already sent out to Matthias, a link to this file. But let's see how this looks like from the other side. Hi, I'm Matthias. I'm waiting for my bank to send me my financial report. I got this link by email from a bank account manager. I click on it and I see this screen. So it asks for a password that I don't know. So I click in request password to verify my identity. Hi, Frank Kolecek here. Hey, how are you, Frank? I would like to access my financial report. Oh, hey, good to see you again. I can give you the password. It is secure one, two, three, four. Oh, well, let me type in the password. All right, great. Here's a financial report.
