Not sure if this is a trick question, what happened to e-mail clients that allow you to do mails 24/7 from a computer?
Hi. sorry, what do you mean with your post?
A lot of services are 24/7 always active, and allow user to read mail (or other things) when he wants. But it is more difficult to break the server than some single pc linked to internet.
In my experience, it is the continuous insertion of user's passwords, IDs, usernames, in a lot of different computers which increases the risk of data copying and stealing, not the fact that so many servers (yahoo, google, apple, hotmail, etc ...) provide 24 hour service everyday.
It is the recognition,by malicious programs, of alphanumeric characters while the user inserts them with the keyboard of the host computer or the forgetting of logout that increase the risks.
A unique connection between two devices (such as PC and iphone) created at a certain time, with a unique qrcode and that can not be cloned in the network and that don't require to enter passwords or other sensitive strings could be safer.
Last year someone stole my google account because I often did login with password in a computer where I worked occasionally. I think that if I could create a temporary, time-limited connection that does not require password or login, with an unique qrcode (that is, the service, for example Apple Mail app, should allow only one connection between only two devices for the same account for all the time that user decides), it would be safer.
This long message to give you reasons for my request, but I understand that the theme of security is very confusing and unclear to many, including me.
Thanks
