I think it is the kind of right place to ask: Is it possible to encrypt the system disc after Linux was installed or so I have to reinstall Linux for that purpose?
Easier said than done. You have to maintain two phones then (updates, keeping charged). You don't want to carry two phones around. Also you have to have two SIM cards/telephone numbers which costs money.
don’t need sim card on second one
it is even more secure that way
it is very common to have different phones for people who work with money transfers (including crypto)
Great idea! How to make sure that the users data stays private without the cloud knowing where the user is surfing. And I wonder how to monetise it? Subscription?
The problem with catch-all inbox is when you have to reply to an email. Then you have to create the email address to be able to send emails from it. Or are there other solutions?
There's no solution to a non-problem. Precisely 3 of the hundreds of the generated email addresses I've given out over the past ~12 years have needed replies. When this happens, I simply reply from an address that actually does exist, while CCing the original generated address and setting it as the reply-to address.
If I ever have to give a generated address out to an actual person, then I'll let them know replies will come from a different address. So far I'd guess 99.999% of the emails I received are transactional emails and/or sent from noreply@...
Far more annoying are a few websites I use that only support magic links for login--my password manager doesn't auto fill them, and some of them I now have a number of accounts at due to inconsistent spelling/formatting.
True, I simplify it a bit based on the capacity of my mail provider. I have like 4 or 5 generic addresses that I give out and use for sending. Sometimes I mix up when sending, but my mail provider (zoho) is pretty decent at keeping track of the addresses anyways.
In a way if I reply, the other party gets upgraded to one of my 5 addresses, so if they send an email to ContosoCoffeeShop@myname.com I might reply from whatever flavour I'm using nowadays or is more appropriate like hello@myname.com
It's like a 3 layer security system, the least privileged get access to one very specific address, if they send me an email which makes sense and I reply, they get upgraded to a bucket. I might sign up directly with a bucket email and skip the most paranoid layer, that's fine.
In general I try to take more care of the newest alias and become more liberal with my older more ruined addresses, alias1@ has like 8 years of signups, while alias5@ has just 1 if any. And I'm sure the list will grow.
Downside is that if there's a leak it's harder to attribute exactly, but at least I can check the recipient to get some kind of hint.
It's more like art than it is a water-tight security protocol. You paint the world with your wacky addresses and occasionally surprise the observant employee with the inverted expectations (usually the name comes before the at)
The problem with catch-all inbox is when you have to reply to an email. Then you have to create the email address to be able to send emails from it. Or are there other solutions?
When you reply, any sensible system will use the address you received it at. Fastmail does this, as do many others (I used Thunderbird for many years, possibly with an extension to do that). To send an email from scratch you just type the address you want in the from field or select from a list. At no point is there any need to create specific addresses, as the catch-all means all addresses are already valid.
That's the reason I don't have scruples to scam Amazon by saying that I haven't received the package when the deliverer just throw it in the first stock of the apartment building without giving notice.
